Usage: Si-69 is a multifunctional silicone rubber and tire additive that has been successfully used in the rubber industry. Its function is to improve the elastic modulus and tensile strength of rubber, significantly improve the wear resistance and compression performance of rubber, reduce rubber viscosity, and save processing energy consumption. Si-69 is best suited for rubber formulations containing hydroxyl fillers in double-bonded polymers or their blends. Applicable fillers include white charcoal smoke, silicate, chalk, etc.; Applicable rubbers include natural rubber (NR), styrene-butadiene rubber (SBR), isoprene rubber (IR), butadiene rubber (BR), nitrile rubber (NBR) and ethylene propylene propylene diene (EPDM).
Packing: plastic drum packing, 1000kg per barrel.
