1. Cooperation Background: Client Faces Selection Barriers Due to Limited Brand Information & One-Sided Product Recommendations from Manufacturers

The buyer is CABLITECH SAS, a high-tech cable manufacturer based in Lyon, France, specializing in new energy vehicle high-voltage cables and rail transit special locomotive cables supplying Alstom, Renault and TotalEnergies, complying with EU REACH, CPR and EN50264 high-end market access standards. Previously long-term purchasers of US Borax original Firebrake zinc borate, the client planned localized substitution of customized modified ultrafine CF zinc borate (low crystal water, composite organic coating, D50=1.2~1.6μm for low-smoke zero-halogen XLPE and EPDM cable formulations) with annual demand of approximately 320 tons of mid-to-high-end modified zinc borate.

Client Pain Points

1. Unfamiliar with China’s zinc borate industrial landscape: No prior knowledge of domestic tier-one brands, technical focuses of each manufacturer and differences across CF modified series models, only able to collect fragmented factory information via exhibitions and chemical websites.

2. One-sided product promotion from manufacturers concealing competitor information: The client contacted five leading domestic zinc borate manufacturers (Taixing New Materials, Wuwei Flame Retardant, Kaisheng New Materials, Yishitong and Donghao Chemical). All manufacturers maintain polite compliance without slandering competitors yet exclusively promote their own product advantages while intentionally concealing strengths and applicable scenarios of rival products:

· Factory A emphasizes powder fineness while omitting coating process weaknesses;

· Factory B highlights thermal stability parameters without disclosing weak free water control performance;

· Factory C underscores low-cost mass production while hiding insufficient precision heavy metal control.

The client received five product brochures with inconsistent parameter labeling standards and divergent performance focus areas, making horizontal benchmarking against CF customized specifications impossible. Blind sample testing incurred high costs (single European sample shipment + third-party TÜV testing exceeding EUR 4,000), halting material selection for nearly one month and suspending the localization substitution project.

Lacking third-party domestic chemical evaluation resources, the client fully entrusted HiSiaddi, a foreign trade service provider, to conduct neutral and objective horizontal breakdowns of mainstream models across five major brands, combining the client’s CF technical requirements (free water ≤0.25%, composite PEG+stearic acid coating, D50:1.2~1.6μm, lead＜8ppm heavy metal limits, compatibility with European cable extrusion processes) to screen well-matched mid-to-high-end brands and models.

2. HiSiaddi Conducts Neutral Research on 5 Leading Domestic Zinc Borate Brands & Mainstream Models, Objectively Sorting Advantages & Disadvantages

Drawing on flame retardant raw material databases, on-site factory visits and third-party CNAS laboratory sample testing, HiSiaddi sets aside manufacturer marketing rhetoric to fairly organize full product details for five leading manufacturers across six dimensions: crystal form technology, coating system, particle size control, impurity management, compliance support and applicable scenarios (objective evaluation without biased praise or criticism).

Brand 1: Shandong Taixing New Materials (Huantai Taixing, State-Owned High-Tech Enterprise, National Benchmark for Halogen-Free Flame Retardants)

Main Models: ZB-2335 General Grade, TX-CF1 Ultrafine Modified Grade, TX-CF2 Low-Water Anhydrous Modified Grade

Mid-to-high-end cable exclusive grades exhibit average batch stability, more suitable for low-end general plastic and coating formulations.

Brand 4: Anhui Yishitong (Listed Inorganic Powder Enterprise, Specializing in Electronic-Grade Powder)

Main Models: ZB-03 Base Zinc Borate, EST-CF Ultrafine Electronic Modified Zinc Borate

· Advantages: Top-tier ultrafine powder grinding technology capable of minimum D50=1.0μm, high-purity electronic-grade raw materials with superior impurity control for precision electronic components.

· Disadvantages: Premium product pricing increases large-tonnage cable procurement costs; limited annual modified zinc borate production capacity unable to support continuous annual orders exceeding 300 tons for the client.

Brand 5: Shandong Donghao Chemical (Fine Customization Manufacturer, Advantages in Small-to-Medium Batch Modification)

Main Models: DH-ZB General Grade, DH-CF Modified Series

· Advantages: Flexible formulations enabling rapid small-batch production and convenient fine-tuning of coating formulas.

· Disadvantages: Insufficient mass production supporting capacity for large orders; REACH compliance requires outsourced agency services extending compliance lead times, unsuitable for the client’s balanced monthly full-year shipment schedule.

3. Combining Client CF Custom Specifications, HiSiaddi Selects 2 Mid-to-High-End Brands & 3 Matching Models

Core client requirements: Annual 320-ton long-term procurement, dual-component composite coating, low free water, full EU compliance, compatibility with new energy cable extrusion and stable mass production batches. HiSiaddi eliminated Kaisheng (weak customization technology), Yishitong (high unit price + insufficient capacity) and Donghao (limited mass production capacity), ultimately selecting two mid-to-high-end brands (Taixing New Materials and Wuwei Flame Retardant) with three segmented CF models gradient-matched to the client’s diverse cable formulations:

Selected Brand 1: Shandong Taixing New Materials, Two CF Models

1. TX-CF1 (Standard General CF): D50=1.4μm, stearic acid + PEG composite coating, free water 0.21%, ZnO/B₂O₃ indicators precisely aligned with client internal control ranges. For the client’s core XLPE low-smoke zero-halogen sheath compound (70% of annual consumption, ~224 tons).

2. TX-CF2 (Low-Water High-Temperature Resistant CF): Thermal weight loss ≤0.6% at 280°C, free water ≤0.18%, custom-developed for the client’s new 150°C high-temperature resistant photovoltaic cable formulations for high-end EPDM high-voltage insulation compounds (~50 tons annual procurement).

Selected Brand 2: Shandong Wuwei Flame Retardant, One CF Model

1. WV-CF (High-Dispersion Modified CF): D50=1.3μm with powder Span≤1.4 and superior dispersion performance. Deployed for the client’s high-filler rail transit cable internal mixing formulation to mitigate excessive melt viscosity and screen clogging (~46 tons annual procurement).

Step 1: Separate Small Sample Shipment (HiSiaddi Coordinates Unified Testing to Cut Client Testing Costs)

HiSiaddi coordinated free provision of 5kg samples from both manufacturers, consolidated packaging and airfreight delivery to French laboratories, eliminating repeated logistics fees from separate manufacturer coordination by the client. The client conducted production line evaluation across three mass-production formulations:

· TX-CF1: Perfect replacement for imported zinc borate in core sheath compounds with no foaming or bloom, LOI=38.8;

· TX-CF2: No volatile gas generation during processing for high-temperature new formulations, meeting heat resistance specifications;

· WV-CF: Superior fluidity in high-filler rail transit cable formulations reducing screen-clogging shutdown frequency by 75%.

Step 2: 500kg Pilot Batch Production Launch

The client issued 500kg pilot orders to Taixing and Wuwei respectively, with goods exported to Marseille Port for continuous 72-hour mass production trials across three production lines, recovering yield rates to match imported material benchmarks, with overall raw material procurement costs reduced by 29% versus US original imports.

Step 3: Finalization of 320-Ton Full-Year Framework Procurement Contract

The client formally signed a contract with volume allocation: Taixing TX-CF1 (224 tons) + TX-CF2 (50 tons), Wuwei WV-CF (46 tons), scheduled for balanced monthly delivery across 12 batches annually. HiSiaddi centrally coordinates production scheduling, factory pre-shipment quality inspection, export compliance and customs clearance & shipping for both manufacturers, supplying exclusive COA, GHS bilingual SDS and SVHC test reports with each batch.
