Silicone masterbatch, commonly known as silicone rubber, is an ultra-high molecular weight polysiloxane modified masterbatch. It is used in compound and extruded plastics, copolymers and elastomer formulations, and can improve processing techniques (such as extrusion Speed, mold filling volume and reduce energy consumption).

Used to improve the surface appearance performance of the product, reduce the COF (coefficient of friction) of the finished parts, and significantly improve the fine molding details and film release; increase the throughput in the manufacturing operation, reduce the driving torque and the pressure of the die Reduce costs in the manufacturing process. The usual addition amount is 0.2~1.6%.
