Customer Pain Points and Zong Yih Rubber Solutions

  1. Rubber Aging and Hardening Issues
    Automotive parts are exposed to frequent impacts, vibrations, and extreme temperature fluctuations (e.g., brake systems), which easily cause rubber to age and harden quickly, affecting ride comfort and driving safety.
    Solution:
    Zong Yih Rubber develops rubber compounds tailored for automotive needs that resist high and low temperatures, impacts, and vibrations. This significantly improves the material’s aging resistance, prolongs part lifespan, and ensures driving safety and comfort.

  2. Environmental and Chemical Corrosion
    Automotive rubber parts are exposed long-term to UV radiation and various chemicals such as fuel and coolant, which can lead to material degradation and cracking.
    Solution:
    Zong Yih offers rubber materials with excellent UV resistance and chemical corrosion resistance to effectively protect parts from environmental and chemical damage, ensuring long-term stable operation.

  3. Seal Failure Leading to Part Damage
    Seals can wear out during prolonged vehicle operation, causing seal failure that allows moisture and contaminants to enter bearings, resulting in part damage and malfunction.
    Solution:
    Zong Yih utilizes highly wear-resistant and water-impermeable sealing rubber materials, optimizing seal structure design to extend the lifespan of bearings and related parts, reducing maintenance costs and downtime risks.

  4. Insufficient Dust Boot Protection
    Critical areas such as the shift lever, ball joints, and suspension systems require effective dust boot protection to prevent dust and moisture intrusion, which can cause component damage and performance degradation.
    Solution:
    Zong Yih produces highly wear-resistant and elastic dust boots that provide stable dust protection, safeguarding key vehicle components for reliable operation and extended service life.
