Highly Dispersible Precipitated Silica is high‑activity precipitated silica as direct replacement for SIPERNAT 238 and ULTRASIL VN3. During rubber kneading and vulcanization, the fine silica particles disperse evenly inside rubber matrix. It significantly boosts tensile strength, tear resistance and abrasion performance of vulcanized rubber, optimizes dynamic hysteresis property, and satisfies technical requirements for green‑tire and technical rubber goods.

Product Detail

Product Overview Highly Dispersible Precipitated Silica (CAS 112926‑00‑8, SIPERNAT 238 / ULTRASIL VN3 Equivalent) is high‑activity precipitated amorphous silica designed for rubber reinforcement. Optimized particle structure reduces agglomeration tendency during internal mixing. Uniform silica network forms within rubber matrix after compounding and vulcanization. The reinforcing silica enhances tensile strength, tear resistance and abrasion‑resistant performance of finished rubber articles. Meanwhile, it lowers rolling resistance for tire formulations and improves dynamic fatigue resistance of industrial rubber components. This precipitated silica is widely applied in green tire tread, rubber hoses, conveyor belts and various technical rubber parts.

Key Features ‑ Excellent dispersibility during rubber internal mixing to avoid hard agglomerates ‑ Delivers strong reinforcing effect for vulcanized rubber, raising tensile and tear strength ‑ Improves abrasion resistance of rubber parts and reduces rolling resistance for tire tread ‑ Optimizes dynamic hysteresis and fatigue performance of rubber compounds ‑ Direct functional equivalent grade for SIPERNAT 238 and ULTRASIL VN3 rubber‑grade silica

Typical Technical Properties ‑ Chemical Type: Precipitated amorphous synthetic silica ‑ Appearance: White free‑flowing fine powder ‑ BET Surface Area: Refer to TDS ‑ Particle Size: Refer to TDS ‑ Oil Absorption Value: Refer to TDS

Applications ‑ Green tire manufacturing: Reinforcing filler for passenger car tire tread compound ‑ Industrial rubber goods: Functional filler for rubber hose, seal and conveyor belt ‑ Rubber compounding workshop: Reinforcing raw silica for technical rubber formulation ‑ Rubber masterbatch plant: High‑activity precipitated silica for modified rubber premix

Processing Recommendation Add highly dispersible precipitated silica at the early kneading stage inside internal mixer. Adjust mixing temperature and mixing duration to achieve sufficient dispersion. Use silane coupling agent as required for tire formulations. Complete lab compounding and vulcanization trials before mass rubber production.

Storage & Handling Store in cool, dry warehouse to prevent moisture absorption. Reseal packaging immediately after opening. Wear dust‑proof mask and protective gloves when handling fine silica powder.
