I. European & American High-end Photovoltaic EVA Film & Electronic Cable Enterprises (Photovoltaic Adhesive Films, High-end Cable Insulation Layers, Electronic Packaging Materials)

(I) Core Pain Points: Insufficient Purity, Excessive Impurities, Poor Thermal Stability, Uneven Crosslinking, Yellowing and Insulation Failure

1.

Insufficient purity (<99%) and high free impurities cause uneven crosslinking density and fluctuating performance of adhesive films/cables High-end photovoltaic adhesive films and electronic cables require TAIC purity ≥99%. Low-purity products contain unreacted allyl alcohol, cyanurate and other impurities, leading to crosslinking efficiency fluctuations with EVA film crosslinking degree deviation exceeding 5%. Photovoltaic modules are prone to delamination and light transmittance attenuation during long-term service; uneven crosslinking of cable insulation layers reduces temperature resistance and breakdown voltage instability, failing to meet UL and TUV certification requirements.

2.

3.

Excessively high acid value (>0.2mgKOH/g) accelerates EVA degradation, resulting in film yellowing and sharp drop in weather resistance Excessive acid value catalyzes hydrolytic oxidation of EVA resin. Photovoltaic adhesive films show obvious yellowing after 6-12 months of outdoor exposure with continuous decline in photovoltaic conversion efficiency; long-term thermal aging of electronic cable insulation layers causes embrittlement, cracking and decreased insulation resistance, posing potential safety hazards.

4.

5.

Poor thermal stability and unbalanced polymerization inhibitor lead to self-polymerization gel during high-temperature processing or incomplete crosslinking Under EVA extrusion (120-150℃) and cable crosslinking (170-180℃) working conditions, insufficient polymerization inhibitor causes self-polymerization caking blocking extruder screens and dies, forcing production line shutdowns; excessive inhibitor results in incomplete crosslinking, sticky films and insufficient mechanical strength of cable insulation layers.

6.

7.

Excessive moisture (>0.1%) generates bubbles in photovoltaic films and pinholes in cable insulation layers Moisture vaporizes during high-temperature processing, forming microbubbles inside EVA films which cause bulging and delamination after photovoltaic module encapsulation; pinhole defects appear in cable insulation layers, drastically reducing voltage resistance and failing high-voltage testing.

8.

9.

Uneven particle size distribution (powder grades) causes poor dispersion during EVA mixing, surface particles and reduced light transmittance of films Excessively large or widely distributed TAIC powder particles disperse unevenly in EVA, forming white particles on film surfaces and increasing haze, impairing photovoltaic module light transmittance and appearance acceptance.

10.

(II) Targeted Solutions

1.

High-purity refined process (purity ≥99.5%) with strictly controlled free impurities for stable crosslinking density Adopt high-vacuum rectification + molecular distillation technology to deeply remove impurities including allyl alcohol and cyanurate, stabilizing main content ≥99.5%. Crosslinking efficiency batch fluctuation <2%, delivering uniform EVA film crosslinking to prevent long-term photovoltaic module delamination; stable temperature resistance and breakdown voltage of cable insulation layers for one-time UL/TUV certification passing.

2.

3.

Precision neutralization + deep deacidification with acid value ≤0.1mgKOH/g to inhibit yellowing and extend weather resistance lifespan Closed-loop neutralization reaction + multi-stage water washing refining strictly controls acid value ≤0.1mgKOH/g to effectively delay EVA degradation.

EVA films are bubble-free with photovoltaic module encapsulation yield ≥99%; dense pinhole-free cable insulation layers achieve 100% passing rate of voltage resistance testing.

8.

9.

Jet milling + precise classification with powder particle size 5-20μm for uniform dispersion and high film light transmittance Special jet milling and screening for powder grades delivers narrow particle size distribution without agglomeration. Complete dispersion during EVA mixing yields smooth particle-free film surfaces with haze ≤2% and 3-5% improved light transmittance.

10.

II. European & American Automotive Rubber Seal & Special Rubber Plastic Product Enterprises (Automotive Sealing Strips, Fluorosilicone Rubber Seals, Shock-absorbing Components)

(I) Core Pain Points: Poor Compatibility, Low-temperature Fluidity Deficiencies, Excessive Residual Impurities Causing Uneven Vulcanization, Seal Leakage and Low-temperature Brittle Cracking

1.

High polar impurities cause poor compatibility with peroxides (DCP) and rubber additives, disrupting vulcanization curves Polar impurities in TAIC trigger side reactions with DCP, anti-aging agents and accelerators, leading to ±15% vulcanization speed fluctuations. Rubber seals suffer under-vulcanization (soft, poor rebound) or over-vulcanization (brittle, crack-prone), exceeding compression set standards and causing door/window seal leakage and shock absorber failure.

2.

3.

High low-temperature viscosity (liquid) / easy caking (powder) lead to poor low-temperature mixing dispersion and uneven product performance Workshop temperatures drop to 5-10℃ in European winters; ordinary liquid TAIC viscosity surges with poor fluidity while powder absorbs moisture and cakes, dispersing unevenly in rubber. Seals feature uneven local hardness with stress concentration and crack upon bending at -30℃, failing automotive low-temperature working condition requirements.

4.

5.

Residual impurities such as allyl alcohol volatilize during vulcanization generating odor and excessive vehicle VOC Impurities volatilize under high-temperature vulcanization (180-200℃) creating pungent workshop odor with excessive VOC and SVHC levels, disqualifying products from supply chains of mainstream automakers including Mercedes-Benz and BMW.

6.

7.

Insufficient thermal aging resistance causes hardening and cracking of seals during long-term service Insufficient TAIC purity forms unstable crosslinking networks; automotive seals harden, crack and peel after 1-2 years of long-term heat and ozone aging leading to seal failure and water/air leakage.

8.

(II) Targeted Solutions

1.

Deep removal of polar impurities for full compatibility with rubber additives and stable vulcanization curves Multi-stage extraction + adsorption refining eliminates polar interfering impurities delivering excellent compatibility with DCP and all rubber additives. Stable vulcanization speed prevents under/over-vulcanization of seals with compression set ≤25% for lasting sealing and shock absorption performance.

2.

3.

8.

III. European & American Unsaturated Polyester FRP & Composite Material Enterprises (Wind Turbine Blades, Yacht Hulls, Industrial Anti-corrosion Pipes)

(I) Core Pain Points: Unstable Reaction Activity, High Curing Shrinkage, Poor Weather Resistance Causing Product Cracking, Deformation and Rapid Aging

1.

Fluctuating reaction activity leads to uneven curing speed, loose interiors and cracking of thick-walled products Unstable TAIC activity creates large batch differences in unsaturated polyester curing speed. Wind turbine blades and thick-walled pipes cure unevenly with loose interiors and insufficient strength; shrinkage stress concentration at thick cross-sections triggers cracking with high scrapping rates.

2.

3.

Excessively high curing shrinkage rate causes product deformation and out-of-control dimensional accuracy Ordinary TAIC features high curing shrinkage leading to warpage and deformation of FRP products post-demolding, dimensional deviation exceeding standards for wind turbine blade airfoils, cracked yacht hull joints and seal failure.

4.

5.

Poor weather resistance and yellowing tendency cause rapid aging and strength attenuation under outdoor service Residual impurities reduce TAIC weather resistance; FRP products (wind turbine blades, outdoor pipes) yellow and chalk after 1 year of outdoor exposure with 20-30% strength loss and shortened service life.

6.

(II) Targeted Solutions

1.

Precisely controlled reaction activity with stable curing speed for dense crack-free thick-walled products Standardized synthesis + online activity monitoring limits TAIC reaction activity batch fluctuation <3%. Uniform curing delivers dense crack-free interiors for thick-walled FRP with qualified strength.

2.

3.

Low-shrinkage modified formulation reduces curing shrinkage rate for dimensionally stable non-deformable products TAIC compounded with low-shrinkage additives cuts curing shrinkage rate by 30%. FRP products show no warpage or deformation post-demolding with qualified dimensional accuracy for wind turbine blades and tight yacht hull joints.

4.

5.

6.

IV. Indian, Southeast Asian General Rubber & Plastic and Wire & Cable Processing Plants (General Cables, Civil Rubber Products, General Plastic Modification, Cost-oriented)

(I) Core Pain Points: Widespread Adulteration, Chaotic Indicator Standards, Deterioration During Storage & Transportation and Incomplete Compliance Causing Production Disruptions and Surging Costs

1.

Low-price adulteration (talc powder, ordinary acrylate) results in insufficient effective content (<90%) and crosslinking failure with soft finished products Genuine TAIC carries high prices; low-end products are heavily adulterated with effective content only 50-80%. Extremely low crosslinking efficiency produces soft, easily deformable cable insulation layers with poor heat resistance; rubber products feature low rebound, wear resistance and aging resistance triggering frequent customer complaints and returns.

2.

3.

Severe fluctuations in key indicators (purity, melting point, acid value, moisture) force frequent production parameter adjustments reducing efficiency Lack of standardized control creates significant batch differences in indicators. Workers frequently adjust vulcanization temperature, duration and addition ratios increasing equipment setup time by 30%, lowering production efficiency and raising scrap rates.

4.

5.

High-temperature high-humidity storage & transportation causes moisture absorption, caking and oxidative discoloration with quality degradation and unusable materials Local ocean shipping and warehouses maintain high temperature and humidity (35-45℃, humidity >80%); ordinary packaged TAIC absorbs moisture, cakes and yellows with declining crosslinking activity, reaching a 15% full barrel scrappage rate.

6.

7.

Incomplete compliance documents (CoA, MSDS, REACH) block formal customs clearance and trigger market inspection cargo detention Missing English compliance documents prevent local filing and sampling inspection, forcing gray channel circulation with unguaranteed payment collection and high detention risks.

8.

9.

Absence of technical support leaves unresolved issues including poor crosslinking, product cracking and odor leading to significant raw material waste Suppliers only deliver goods without formulation guidance; factories blindly adjust formulas when abnormalities occur increasing TAIC and rubber plastic raw material waste by 20%.

10.

10.

V. Overseas Chemical Repackaging & Rubber Plastic Additive Trading Distributors (Regional Repackaging, Small Packaging, Supporting Supply)

(I) Core Pain Points: Adulteration and Dilution, Damaged Leaking Packaging, Missing Qualifications, Warehouse Deterioration Leading to Damaged Reputation and Lost Customers

1.

Widespread adulteration and dilution with cheap monomers/solvents, falsely labeled purity triggering mass after-sales compensation claims Unscrupulous merchants dilute TAIC and falsely label purity (marked 99% actual 80%). Downstream factories suffer crosslinking failure and scrapped finished products, forcing distributors to pay heavy compensation, lose customers and collapse channel credibility.

2.

3.

Insufficient packaging strength and poor sealing cause bag breakage/liquid leakage during ocean shipping with cargo loss and logistics disputes Thin ordinary cardboard drums/iron barrels with weak seals break and leak powder/liquid under ocean stacking and jolting, causing material loss, cross-contamination of container goods, logistics deductions and compensation claims.

4.

5.

Lack of light and moisture protection leads to oxidative discoloration, caking and activity attenuation during storage TAIC is sensitive to light and heat; simple packaging causes yellowing, rising viscosity, powder caking and activity decline during storage. High-end customers reject full batches upon inspection.

6.

7.

Missing hazardous chemical/environmental qualifications (SDS, dangerous goods appraisal, REACH) block access to European & American high-end supply chains Absence of compliance documents prevents supplier audits by leading rubber plastic enterprises and brand owners, limiting business to low-end circulation with thin profit margins.

8.

9.

Unsealed repackaging facilities allow impurity and moisture ingress deteriorating small-batch quality with low repeat purchase rates Open repackaging exposes TAIC to air and moisture increasing acid value, reducing activity and causing yellowing with unstable small-pack quality and continuously declining terminal customer repurchase rates.

10.

(II) Targeted Solutions

If you require more professional and in-depth analysis on TAIC selection, please contact HiSiaddi customer service.

I. Core Comprehensive Global Sourcing Factors (Full-dimensional Pre-assessment to Avoid Compliance, Quality and Supply Risks)

Before confirming suppliers and product grades, complete a full-dimensional pre-assessment first. This is the core prerequisite to guarantee stable delivery of cross-border orders and reduce after-sales issues in production.

First, strictly verify regulatory requirements and market access qualifications for target countries and regions. As a fine chemical additive specially used for polymer materials, TAIC is applied in highly regulated sectors including wires & cables, automotive rubber and plastic accessories, daily necessities, food contact materials, photovoltaics, and children’s rubber and plastic products. Global chemical safety and environmental regulations vary significantly.

· EU market: Products must complete REACH registration and SVHC substance of very high concern screening; electronic cables and automotive rubber and plastic products shall comply with RoHS 2.0; products for children’s contact shall additionally meet EN 71-3 toy safety standards.

· North American market: TSCA chemical inventory listing is mandatory; food and drinking water contact rubber and plastic materials need relevant FDA testing; cables and photovoltaic materials shall follow North American industry specifications.

· Japan, South Korea and Australia impose strict control over residual monomers, heavy metals, organic impurities and volatile substances.

· Southeast Asia, the Middle East and South America adopt general industrial safety standards. If goods are re-exported to Europe and the United States as end destinations, a full set of international certifications must be provided.

Customs authorities worldwide conduct regular inspections of multi-lingual MSDS, batch-by-batch COA reports and third-party test certificates, requiring consistent information on certificate issuers, manufacturing factories and shipment batches. Missing qualifications or inconsistent information will directly lead to cargo detention and return. Purchasers must verify all items in advance.

Second, fully match downstream production processes and equipment working conditions. TAIC is available in three forms: liquid, solid crystal and powder, with colorless to pale yellow transparent liquid as the mainstream form; flake and powder grades are also available. It is mainly used in rubber mixing, plastic granulation, extrusion molding, radiation crosslinking, high-temperature compression molding and resin curing processes. This product directly determines the crosslinking density, heat resistance and electrical properties of polymer materials. Downstream processes are highly sensitive to purity, melting point, moisture, residual impurities and thermal stability:

· Insufficient purity and excessive residues such as allyl alcohol and isocyanuric acid will greatly reduce crosslinking efficiency, increase volatile matter and odor, and impair heat resistance and insulation performance of finished products.

· High-temperature mixing and continuous extrusion production lines require products with strong thermal stability that do not decompose or volatilize under processing temperatures.

· For automated batching and closed granulation production lines, focus on particle size, fluidity and anti-caking performance of powder/flake products; for liquid products, prioritize consistent batch viscosity to avoid batching ratio deviations.

· In multi-additive compound systems, TAIC must have good compatibility with vulcanizing agents, initiators, resins and fillers without precipitation or blooming during long-term use.

· Radiation crosslinking processes demand higher product purity and low volatility to prevent by-product generation during irradiation.

New customers are recommended to send samples for small-scale and pilot tests in advance to verify crosslinking efficiency, heat resistance and electrical properties of finished products.

Third, distinguish end product positioning and long-term service environments.

· High-value products such as high-end wire and cable insulation layers, photovoltaic encapsulation materials, automotive high-temperature rubber and plastic accessories, fluoroplastic modification and aerospace composite materials must adopt high-purity refined grades with low residues, low volatility and high thermal stability.

· Rubber and plastic products for food and children’s contact exported to the EU, North America and Australia must strictly control migratable heavy metals and toxic organic residues.

· General industrial rubber miscellaneous parts and general plastic modified materials can adopt standard industrial grades to balance procurement costs.

· Products operating under long-term high temperature, strong outdoor sunlight and radiation environments shall be assessed for aging resistance, high temperature resistance, radiation resistance and stable electrical performance after crosslinking to avoid rapid performance degradation during long-term service.

Select products according to end positioning while balancing product quality and operating profits.

Fourth, evaluate supplier production capacity, raw material supporting capacity and long-term supply stability. TAIC is synthesized using cyanuric acid and allyl alcohol as main raw materials through addition, esterification, rectification, purification and forming processes. High-purity products require stringent rectification and impurity removal processes. Purchasers with long-term large global orders, multi-port distribution and peak season bulk replenishment shall prioritize large-scale factories equipped with continuous synthesis and multi-stage rectification production lines and self-sufficient core raw material supply. Such enterprises are less affected by upstream raw material price hikes and regional environmental inspections, with low capacity fluctuations in off-peak and peak seasons, and highly consistent batch physical and chemical indicators and application performance. Meanwhile, confirm whether suppliers support direct delivery from major domestic export ports including Qingdao, Shanghai, Ningbo and Tianjin, and flexibly accept full-container, LCL and small-batch urgent orders. In addition, inspect enterprise laboratory configuration to confirm full physical and chemical testing, crosslinking efficiency, thermal stability and electrical performance testing capabilities, and cooperation with international third-party institutions such as SGS, Intertek and BV for sampling and re-inspection.

Fifth, plan cross-border packaging, transportation and long-distance storage & transportation solutions. Liquid TAIC is an irritant liquid chemical, while solid/powder TAIC is not classified as high-risk goods with fewer global sea, land and air transport restrictions. Storage and transportation characteristics of the product:

· Liquid grades thicken at low temperatures and volatilize and oxidize at high temperatures;

· Solid grades have low hygroscopicity but tend to cake at high temperatures and darken under prolonged light exposure.

For ocean shipping and tropical high-temperature routes:

· Liquid products adopt sealed galvanized iron/plastic drums (standard 200kg drums for regular production, IBC totes for large-scale production lines); containers shall be protected from light and heat to avoid oxidative discoloration and volatilization.

· Solid/powder products adopt 25kg packages of thick woven bags lined with PE film or paper drums; heat insulation is also required in high-temperature areas to prevent caking. Additional moisture-proof measures are unnecessary in high-humidity regions, but packaging integrity must be fully sealed.

During storage and transportation, mixing and stacking with strong acids, strong alkalis and strong oxidants are strictly prohibited. Warehouses shall be cool and well-ventilated. The recommended storage temperature for liquid TAIC is 10~30℃, while solid TAIC shall be stored below 35℃. Follow the first-in, first-out principle to avoid deterioration from long-term storage.

Finally, consider product customization services and supporting polymer formulation technical capabilities. Different rubber types, plastic systems and crosslinking processes have personalized requirements for TAIC form, purity, residual impurities, viscosity and particle size. Mature factories can provide customization including form switching, deep purification of indicators and particle size screening. Professional suppliers can also offer formulation guidance to optimize addition ratios matching peroxide, sulfur and radiation initiation systems, improving heat resistance, insulation and anti-aging performance of finished products and solving common issues such as uneven crosslinking, excessive volatile matter and precipitation. Comprehensive technical services are a key bonus factor for long-term cooperation.

II. Universal Basic Indicators for All Product Grades (Mandatory Inspection for All Purchasing Scenarios, Bottom-line Quality Standards)

Regardless of product form, grade or target global region, the following physical and chemical indicators are mandatory standards for sampling inspection upon factory delivery and arrival of every batch. Failure to meet indicators will directly reduce crosslinking effects, cause performance defects and mass scrapping of polymer finished products, and are non-negotiable quality bottom lines.

1. Active ingredient purity (main TAIC content) Purity is the core indicator determining crosslinking efficiency and comprehensive performance of finished products. Higher active ingredient content means lower levels of allyl alcohol, monomers and high-boiling impurities, resulting in a more stable crosslinking system. Industry classification standards:

· General industrial grade ≥95.0% purity

· Standard rubber crosslinking grade ≥98.0% purity

· High-end cable/photovoltaic/food contact grade ≥99.0% purity

Insufficient purity directly reduces crosslinking density, significantly impairs heat resistance, strength and insulation performance of finished products, increases volatile matter and generates odor, making this the top priority for inspection.

1. Acid value Represents the content of acidic impurities in the system, affecting storage stability, substrate corrosion resistance and compatibility of compound systems.

· General grade: acid value ≤0.2 mgKOH/g

· High-end low-corrosion grade: strictly controlled ≤0.1 mgKOH/g

Excessively high acid value accelerates product oxidative deterioration and interferes with vulcanization and crosslinking reactions, which is a strict requirement for cables and precision rubber and plastic products.

1. Moisture content Although TAIC has low overall hygroscopicity, trace moisture still affects high-temperature processing stability and electrical performance.

· General grade: moisture ≤0.10%

· High-end insulation material grade: moisture ≤0.05%

Excessive moisture generates bubbles during high-temperature processing and reduces cable insulation strength.

1. Color number (Pt-Co scale) Liquid TAIC is normally colorless to pale yellow transparent liquid, while solid TAIC is white crystal. Color number reflects the content of oxidized impurities.

· General industrial grade: color number ≤60#

· Standard grade: color number ≤40#

· High-end transparent product/insulation material grade: color number ≤20#

High color number indicates severe oxidative deterioration accompanied by increased volatile matter and degraded performance.

1. 

Viscosity (liquid) / Melting point (solid) Viscosity of liquid products determines batching uniformity and conveying fluidity with stable viscosity required across batches. Standard melting range of solid TAIC is 23~26℃; narrower melting range indicates purer components and more stable molten processing status. Excessively wide melting range or large viscosity fluctuations will lead to out-of-control processing and uneven crosslinking.

2. 

3. 

Heating loss (volatile content) Characterizes low-boiling residual impurity content.

4. 

· General grade: heating loss ≤0.3%

· High-end low-volatility cable/radiation crosslinking grade: ≤0.15%

Excessive volatile content releases harmful substances during high-temperature processing and irradiation, forming pores and odor, which seriously affects safe use of cables and sealing parts.

III. Specialized Indicators by Global Application Scenario (Classified by End Use with Differentiated Control Priorities)

Classified specialized test indicators are defined for TAIC’s four mainstream global application fields, with different control focuses for each scenario. These also serve as the basis for distinguishing product grades, pricing and matching international regulations, allowing precise quality control aligned with end products.

(I) Wires & Cables, Photovoltaic Materials and High-end Rubber & Plastic Products (High-end Markets in Europe, the U.S., Japan and South Korea)

This is TAIC’s core high-end application field, featuring strict control standards focused on high insulation, low volatility, high heat resistance, stable crosslinking and radiation resistance.

1. Crosslinking efficiency: Crosslinking degree tested under fixed formulation and process with minimal batch fluctuation to guarantee consistent performance of cables and photovoltaic materials.

2. Thermogravimetry (thermal stability): Simulate high-temperature extrusion and irradiation working conditions to test volatilization and decomposition under high temperatures, requiring stable performance without decomposition.

3. Volume resistivity: Ensure cable insulation performance with strict control over inorganic ions and conductive impurities.

4. Heavy metal content: Comply with RoHS standards with restricted substances including lead, cadmium, mercury and hexavalent chromium below regulatory limits.

5. Anti-precipitation performance: High-low temperature cycle aging test with no migration or blooming during long-term use to avoid impairment of insulation and sealing effects.

(II) Food Contact and Children’s Rubber & Plastic Products (Key Regulated Categories in Europe, the U.S. and Australia)

Based on universal indicators, align with safety regulations with core focus on low migration, non-toxicity, low irritation and low residues.

1. Migratable heavy metals: Tested in accordance with EN 71-3, CPSIA and FDA standards with far stricter limits than general industrial materials, serving as a veto item for market access.

2. Toxic organic residue screening: Strictly control harmful residual monomers such as allyl alcohol and cyanuric acid to reduce toxicity and sensitization risks.

3. Low volatile matter: Minimize small molecule precipitation to guarantee safe contact use.

(III) General Rubber and Ordinary Plastic Modification (General Industrial Markets in Southeast Asia, the Middle East, South America and Eastern Europe)

Prioritize basic crosslinking capacity and cost control with moderately relaxed indicator requirements. Focus on three core basic indicators: purity, acid value and volatile content to ensure normal crosslinking reactions and basic mechanical properties of finished products. Slight fluctuations in color number and viscosity are tolerable to balance procurement costs and production efficiency.

(IV) Radiation Crosslinked Products and High-temperature Resins (Radiation Cables, High-temperature Resistant Composites, Global General Use)

Core control requirements include ultra-high purity, ultra-low volatility, radiation resistance and excellent thermal stability. Additional irradiation aging and long-term thermal-oxidative aging tests are conducted to assess product stability under strong radiation and continuous high temperatures. Further tighten control over moisture, volatile matter and impurities to avoid pores and performance degradation originating from raw materials.

IV. Supplementary Cross-border Sourcing Dimensions (Qualification Certifications, Customization Services, Supply Stability and Product Drawbacks)

Beyond physical and chemical and application indicators, cross-border global procurement also requires simultaneous attention to qualification certifications, acceptable customization, supply capacity and inherent product drawbacks to secure long-term stable cooperation.

(I) Mandatory Global Market Qualification Certifications

Universal basic documents worldwide: ISO9001 quality management system certificate, multi-lingual MSDS, batch-by-batch COA reports and SGS basic physical and chemical test reports.

· EU market: REACH registration, SVHC screening, RoHS 2.0; add EN 71-3 for children/food contact products.

· North American market: TSCA chemical inventory listing, FDA (food contact products), CPSIA (children’s products).

· Japan, South Korea and Australia: Local chemical inventory filing, special testing for residual monomers and heavy metals. All certificates must be within valid periods with consistent information across manufacturing factories, brands and batches.

(II) Acceptable Product Customization Services

Major domestic TAIC manufacturers serving global B-end customers regularly support multiple personalized customizations:

1. Form customization: Free switching between liquid, flake and powder to adapt to different batching and processing equipment.

2. Deep purification: Further reduce residual monomers, volatile matter and ion content for high-demand scenarios including cables, photovoltaics and food contact materials.

3. Indicator fine-tuning: Precisely control acid value, color number and viscosity to match customers’ exclusive processes.

4. Powder modification: Anti-caking treatment and improved fluidity for powder grades to adapt to long-distance ocean shipping and automated batching.

5. Packaging customization: Flexible switching between 200kg drums, 25kg bags and IBC totes, plus customized multi-lingual outer packaging labels.

6. Pre-mixed compounding: Pre-blend with peroxide crosslinkers and vulcanization additives per customer ratios to simplify downstream processes.

(III) Key Judging Criteria for Supply Stability

Prioritize large-scale factories with self-sufficient raw material supply, continuous synthesis and multi-stage rectification production lines. Multi-stage rectification is the core process to control purity, residues and volatile content, while continuous production drastically narrows batch differences. Self-sufficient raw material supply mitigates risks of upstream raw material price hikes and supply disruptions. Standard lead time for full-container orders is 7~12 days, with direct delivery from multiple ports and support for urgent small-batch rush orders. Small-scale intermittent production equipment has weak purification capacity and high residual impurities, unsuitable for high-end cable, photovoltaic applications and long-term large-volume cross-border global orders.

(IV) Inherent Product Drawbacks and Procurement Risk Reminders

1. Liquid TAIC thickens at low temperatures with reduced fluidity; temperature control is required for storage and transportation in cold regions to avoid pipeline conveying difficulties.

2. Liquid products are prone to oxidative discoloration and increased volatility under high temperatures and strong light; shipping containers must be protected from light and heat.

3. Solid TAIC easily cakes under high temperatures; stacking height shall be limited and warehouse temperature strictly controlled.

4. Liquid TAIC irritates skin and respiratory tracts; labor protection equipment must be worn during loading/unloading and production, with MSDS accompanying all shipments.

5. Excessive addition ratio leads to over-crosslinking of rubber and plastic finished products, resulting in brittle materials and reduced toughness; gradient tests on new formulations are required in advance.

6. Ultra-high-purity, low-ion cable/food-grade products involve complex purification processes with higher selling prices than general industrial grades, slightly increasing formulation costs.
