Downstream process integration

• Introduced during the wet mixing stage with silane coupling agents to facilitate dispersion and polymer interaction; followed by completion of the masterbatch on Banbury or intermix mixers prior to final roll milling

Final product types

• Low rolling resistance passenger car tire treads
• High-performance and all-season tire compounds
• Light truck and EV tire tread layers

2. Conveyor Belt Rubber Reinforcement

Heavy-duty conveyor belt producers depend on precipitated high surface area silica to replace or supplement carbon black, enhancing flex endurance, lowering weight, and extending the operational window in abrasive, high-load environments.
