HiSiaddi Assists Mid-Size Thai Tire Manufacturers with Si-69 Silane Coupling Agent Selection

Project Background: Foreign Tire Manufacturer Faces Decision Deadlock When Switching Domestic Si-69 Suppliers

1.1 Client Production & Procurement Requirements

• A      local Thai producer of semi-steel radial green tires and rubber vibration      dampers with long-term procurement of Evonik imported Si-69

• Cost-reduction      initiatives in December 2025 drove a shift to Chinese supply chains, yet      the procurement team lacked familiarity with China’s Si-69 market      landscape

1.2 Core Pain Points Encountered During Direct Domestic Factory Outreach

• Manufacturers      only promoted their proprietary products without neutral cross-brand      benchmarking, preventing differentiation between production processes and      end-product compatibility

• Cost-performance      dilemma: Low-cost grades raised concerns over tire wear resistance and      rolling resistance compliance, while premium models inflated manufacturing      overheads

1.3 Dual Production Lines with Differentiated Quality Standards

1. Mid-to-high-end      green tire production line: EU tire label regulation compliance      requirements, including low VOC emissions, consistent batch performance      and compatibility with high silica-filled formulations

2. Standard      rubber component production line: Cost efficiency prioritized with      consistent supply as the primary target

HiSiaddi Neutral Cross-Brand Benchmarking & Customized Matching Solutions

2.1 Four Leading Domestic Export Si-69 Brands Selected for Independent Comparative Testing

Neutral performance evaluations were conducted for Jianghan New Materials, Hongbai New Materials, Chenguang New Materials and Nanjing Shuguang, eliminating bias from single-supplier sales pitches.

2.2 Multi-Dimensional Core Parameter Benchmarking

1. Performance      metrics: Sulfur content, free mercaptan, batch CV fluctuation, coupling      efficiency and sulfur chain stability tested side-by-side

2. Distinct      core competitive advantages per brand

• Jianghan      New Materials: Comprehensive performance matching imported Evonik      standards

• Hongbai      New Materials: Industry-leading low VOC and low carbon footprint      performance

• Chenguang      New Materials: Strong capability for custom formulation tuning

• Nanjing      Shuguang: Mature industrial-grade stability with superior cost      competitiveness

2.3 Price Tier & Model Margin Analysis

FOB prices segmented into three categories: standard liquid, low-VOC modified and solid pellet grades, with clear pricing logic for premium high-end and mid-range economical variants.

2.4 Cross-Border Export Support Service Comparison

Four key service dimensions were evaluated: after-sales quality assurance, lead time, peak season supply guarantees and on-site technical support.

Customized Line-Specific Selection & Final Project Outcomes

3.1 Matching Solution for High-End Green Tire Production Lines

Recommended Hongbai HB-Si69LV and Jianghan JHSI-69L low-VOC modified grades

• Key      specifications: Free mercaptan <0.1%, batch CV ≤2%, meeting EU carbon      footprint supply chain standards

• Delivered      value: Reduced tire rolling resistance, improved wear resistance, full      import substitution and approximately 12% lower procurement costs

3.2 Matching Solution for Civil Rubber Vibration Damper Production Lines

Chenguang CG-Si69 standard universal grade selected, eliminating premium performance markups for mass low-cost production.

3.3 Final Project Results: Neutral Analysis Report & Sustained Repeat Orders

A comprehensive neutral supplier selection analysis report was delivered, paired with sequential small-batch sampling and supporting process adaptation technical services. Full-scale production using the two segmented grades maintained zero quality fluctuations, prompting the client to sign a long-term fixed procurement contract with consistent repeat orders, affirming the value of HiSiaddi’s neutral integrated procurement services.
