HiSiaddi horizontally analyzed strengths and weaknesses of 5 major domestic brands, accurately screening 2 premium manufacturers and 3 matching grades for procurement launch
Headquartered in Hamburg, Germany, NovaPlast is a specialized German manufacturer of high-end eco-friendly masterbatch and modified engineering plastics with 28 years of expertise in three core segments: food-contact PP masterbatch, new energy vehicle modified masterbatch, and transparent PC color masterbatch. Its supply chain covers BASF supporting plastics, Bosch automotive interiors, and local German dairy food packaging manufacturers. All products strictly comply with EU REACH, German LFGB food contact, RoHS, and EU VOC environmental control standards. The company previously sourced original imported EBS from Germany’s DEUREX on a long-term basis with a stable annual EBS purchase volume of 176 tons split into 72 tons food-grade, 68 tons automotive modification grade, and 36 tons transparent engineering plastic grade.
This client features fixed formulations, strict raw material indicator control, zero tolerance for significant raw material performance fluctuations, and prioritizes quality over low pricing, clearly distinguishing it from low-end traders purchasing bulk inventory with freely adjustable formulations.
Hit by surging local European grease raw material prices, capacity maintenance shutdowns at overseas manufacturers, extended delivery lead times of 120 days for imported EBS, and a 32% increase in procurement costs, NovaPlast launched a localization substitution research program for domestic EBS, planning small-batch sampling from high-quality domestic EBS brands before finalizing an annual long-term agreement. The client initially contacted five leading domestic EBS manufacturers: Changzhou Kesai Chenggong, Jiangxi Weike, Qingdao Sainuo, Zhejiang Tonghuawang, and a general EBS manufacturer in Shandong for quotation and sample delivery. However, a widespread industry issue emerged: sales teams at each factory only promoted their own brands, avoiding objective discussion of competitors’ advantages while unilaterally claiming their products fit all application scenarios. The German procurement engineers lacked familiarity with China’s additive industry and could not distinguish indicator gaps between standard domestic EBS and high-end modified EBS. After receiving five biased recommendation documents from individual manufacturers, sample selection fell into disarray. Some submitted samples presented defects including poor dispersion, high-temperature precipitation, and yellowing in transparent materials during production trials, prompting the client to suspend independent brand selection and fully entrust HiSiaddi to leverage domestic industry resources to conduct horizontal brand evaluation, objectively compare pros and cons, and screen EBS products matching its three production lines.
Mandatory selection benchmarks specified by the client (benchmarked against German imported EBS):
1. Physical & chemical indicators: acid value ≤3.6mgKOH/g, free fatty acid ≤0.15%, heating loss ≤0.2%;
2. Powder specifications: ≥99% pass rate for 325-mesh ultrafine powder for food/transparent grades; particle or 200-mesh powder optional for automotive grades;
3. Performance requirements: no dispersed white spots under high-titanium dioxide loading, no bloom precipitation under 230℃ processing, no yellowing in transparent PC systems.
HiSiaddi formed a team of additive technical specialists and masterbatch application engineers to sort core models of five brands based on the client’s three application scenarios (food, automotive, transparent engineering plastics), objectively listing strengths, weaknesses, and suitable fields for each brand to break biased single-manufacturer promotion barriers:
· Core grades: KS-980 (high-purity powder EBS), KS-995 (polar modified EBS), KS-G general particle EBS
· Strengths: National standard drafting participant for EBS, self-built polymer R&D lab, feedstock sourced from imported palm-based stearic acid. All series hold FDA, LFGB, and REACH certifications with exceptional control over free impurities. Modified grades feature polar molecular side chains for strong pigment wetting and dispersion, ideal for high-end food-grade and transparent engineering plastic applications;
· Weaknesses: Relatively high product pricing, average cost performance for general particle grades, high minimum order quantity for small-batch samples;
· Suitable applications: Client food masterbatch and transparent PC masterbatch.
· Core grades: WK-EBS01 (high-purity food-grade powder), WK-M polar modified EBS
· Strengths: High-tech enterprise specializing in bio-based modified bisamides with self-optimized three-stage temperature-controlled synthesis processes delivering low volatility and low precipitation, heat resistance exceeding 290℃, minimal VOC emission under high-temperature extrusion, outstanding compatibility with automotive modified materials;
· Weaknesses: Limited variety of general standard grades, constrained ultrafine powder production capacity, slightly extended lead time for bulk stock;
· Suitable applications: Client new energy vehicle interior modified masterbatch.
· Core grades: SN-EBS ultrafine powder, SN-G particle EBS
· Strengths: Fully automated end-to-end production lines with high whiteness and excellent thermal stability, balanced internal and external lubrication, abundant spot inventory, superior cost performance relative to top premium brands, compatible with both general and modified formulations;
· Weaknesses: Internal control indicators for high-purity food-grade grades lag behind Kesai and Weike, mediocre performance in high-end transparent materials;
· Suitable applications: Mid-to-low-end general masterbatch, incompatible with client premium food and transparent production lines.
· Core grade: EB-FF standard diffusion powder
· Strengths: Large-scale production capacity, low pricing, dominant market share in China’s low-end masterbatch sector, abundant spot supply of 200-mesh powder;
· Weaknesses: Synthesized with domestic industrial stearic acid with elevated free fatty acids and small-molecule impurities, lacking full EU food compliance certifications, prone to precipitation under high temperature, unable to meet EU LFGB and food packaging access requirements;
· Suitable applications: Low-end ordinary plastics and filled masterbatches, directly eliminated from the client’s candidate list.
· Core grade: Industrial-grade EBS powder
· Strengths: Lowest market pricing, strong bulk supply capacity;
· Weaknesses: Only meets basic national standard indicators without high-end modification processes, excessive acid value and volatile fractions, no EU compliance certificates, severe bloom and poor dispersion during production trials;
· Suitable applications: Low-end recycled plastics and cheap filled products, inconsistent with mid-to-high-end client requirements.
Based on horizontal test data from five brands and differentiated demands across NovaPlast’s three production lines, HiSiaddi eliminated Tonghuawang, the low-cost Shandong manufacturer, and Sainuo’s non-premium grades, ultimately selecting two domestic mid-to-high-end leading brands — Changzhou Kesai Chenggong and Jiangxi Weike — with three exclusive grades matching each client production line:
1. Kesai Chenggong KS-980 high-purity ultrafine EBS (325-mesh powder) → For food packaging PP masterbatch Fully passes German LFGB food contact testing, ultra-low free fatty acids, uniform dispersion of high-loading titanium dioxide free of white spots, perfectly matching production conditions for Nestlé food packaging masterbatch.
2. Kesai Chenggong KS-995 polar modified EBS (325-mesh powder) → For transparent PC color masterbatch Polar modified molecular structure eliminates yellowing under high-temperature processing without compromising substrate transparency, resolving the client’s transparent masterbatch yellowing issue and matching performance of original imported products.
3. Jiangxi Weike WK-M modified EBS (200-mesh powder) → For new energy vehicle interior modified masterbatch Low volatility and low precipitation, minimal smoke emission under 225℃ high-temperature extrusion with VOC compliant with German environmental regulations, suitable for PP + glass fiber high-filler automotive interior formulations.
HiSiaddi coordinated 5kg samples from both manufacturers to be airfreighted to Hamburg, Germany. NovaPlast conducted continuous full-condition pilot production across its three lines for 35 consecutive days:
· Food masterbatch: KS-980 finished products passed third-party German food migration testing with zero precipitation and fish eyes, successfully entering dairy packaging supply chains;
· Transparent PC masterbatch: KS-995 colored transparent products deliver full clarity without yellowing or pigment agglomeration, meeting high-end optical color matching standards;
· Automotive modified masterbatch: WK-M modified plastic injection-molded interior parts show zero bloom after 30 days of room-temperature storage, passing incoming inspection by Bosch automakers.
Performance of all three grades fully matched Germany’s DEUREX original EBS, cutting the client’s comprehensive raw material procurement cost by 28.6% and shortening ocean freight lead times from 120 days to 38 days. NovaPlast reduced its procurement volume from the German manufacturer and signed a quarterly annual supply agreement for 176 tons with HiSiaddi (72 tons KS-980, 36 tons KS-995, 68 tons WK-M). The contract stipulates HiSiaddi will coordinate production scheduling between the two manufacturers, handle unified customs export declaration, and provide full-cycle technical after-sales service, with free grade fine-tuning and formulation support for future new product R&D.
Sales teams at domestic EBS manufacturers are bound by sales targets and only promote their own products, refusing to objectively analyze competitors’ strengths and applicable weaknesses. Overseas mid-to-high-end clients lack information on China’s market and risk selecting unsuitable grades under biased guidance, leading to defective production trials and material waste. Low-end buyers can offset raw material defects via low-cost feedstock and formulation adjustments, but European and American mid-to-high-end clients rely on formulations validated over years that cannot be altered, and incorrect grade selection directly triggers full production line shutdowns and failed incoming inspection by end-brand customers.
Unlike low-end buyers focused solely on unit price and random standard spot purchases, European mid-to-high-end masterbatch enterprises prioritize grade selection aligned with end-use applications, full indicator benchmarking against imported materials, and paired compliance and technical support. They require third-party service providers to break manufacturer sales bias via neutral cross-brand evaluation and reverse-engineer product selection standards from end-user processing demands.
Drawing on comprehensive additive industry expertise, HiSiaddi operates independently of single-manufacturer profit incentives to conduct objective horizontal evaluation of mainstream domestic brands. It translates client end-process requirements into grade selection criteria to screen optimal product combinations, mitigating client risks of selecting low-quality raw materials while connecting premium domestic mid-to-high-end EBS manufacturers to European high-end supply chains. HiSiaddi builds long-term partnerships with premium overseas clients via neutral selection consulting services.
