Our partner client is TYRES GERMANY, a high-end tire and rubber group headquartered in Hanover, Germany, a leading European manufacturer of mid-to-high-end passenger tires, new energy vehicle low rolling resistance tires and premium construction machinery rubber components, supplying mainstream automakers including Mercedes-Benz, BMW and Volkswagen. The company complies with EU REACH, RoHS, tire VOC limits and automotive-grade rubber mechanical performance standards, imposing stringent requirements on raw material purity, batch stability, environmental indicators and silica system compatibility, representing a typical technology-driven mid-to-high-end client.
The client’s annual Si-69 silane coupling agent procurement volume totals approximately 50 tons for silica-reinforced tire tread production. Its core objective is to replace its existing Evonik Si-69 supply from Germany to cut procurement costs without compromising product quality. As a first-time buyer entering China’s supply market, the client had no familiarity with China’s Si-69 brand landscape, technical tiers and model differentiations. After engaging three mainstream domestic manufacturers, all suppliers only promoted their own products, avoided objective cross-brand comparison and exaggerated their own product compatibility, trapping the client in an information vacuum: unable to judge which brand/model aligned with its premium tire formulation and fearing costly mass production quality risks, the client’s procurement plan stalled. It ultimately entrusted HiSiaddi to deliver neutral, professional, unbiased brand and model screening services.
1.
Zero Domestic Brand Awareness & Inability to Distinguish High/Low Technical Tiers The client only recognized international brands such as Evonik and Shin-Etsu, with no understanding of the technical strength, product positioning and premium application suitability of leading domestic Si-69 manufacturers including Jianghan New Materials, Jiangxi Hongbai New Materials, Jiangxi Chenguang New Materials, Shandong Yuanhe New Materials and Nanjing Bopai. It could not differentiate universal grades from premium customized specialized variants.
2.
3.
Manufacturers Only Promote Their Own Products & Refuse Objective Horizontal Benchmarking The three large domestic manufacturers contacted operated with obvious self-serving bias:
4.
· Only emphasized self-stated advantages of “high purity and stable quality” without disclosing inherent weaknesses (e.g. excessive residual solvents at one manufacturer, large batch fluctuations at another);
· When asked about competing brands, only offered dismissive commentary without objective disclosure of competitors’ strengths (e.g. Hongbai’s leading sulfur-containing silane technology, Chenguang’s robust customization capacity);
· All manufacturers claimed “full compatibility with premium tires” without supporting third-party test data or verified premium client case studies, leaving the client unable to validate performance claims.
1.
Unstandardized Model Nomenclature Complicates Formulation Matching China’s Si-69 product lineup lacks unified naming standards. Beyond universal grades, each manufacturer launched modified, low-VOC, high-purity and low-temperature stable derivative models (e.g. Hongbai HB-69, Jianghan JH-69, Chenguang CG-69LT) with no public standardized performance benchmark data, making it impossible for the client to identify variants suited to its low rolling resistance, high wear resistance, light-colored tread formulation.
2.
3.
Extremely High Trial & Error Costs Discourage Blind Bulk Orders Premium tire formulations are highly sensitive to Si-69 purity, sulfur content, residual ethanol and batch stability. Selecting an incompatible model triggers uneven silica dispersion, tread yellowing, vulcanization fluctuations and unqualified rolling resistance metrics, directly invalidating automotive OEM certifications. Single batch trial failure losses can exceed one million euros, driving urgent demand for neutral third-party precise model selection guidance.
4.
Drawing on 10 years of chemical foreign trade experience, a library of premium rubber client case studies and third-party laboratory test data, HiSiaddi delivered an unbiased, conflict-of-interest-free comprehensive evaluation report covering five top domestic Si-69 manufacturers across six core dimensions: technical strength, product positioning, flagship models, key technical indicators, applicable scenarios and inherent limitations.
