1.HENGDA-Si69 is a multifunctional additive that has been successfully applied in the silicone rubber and tire industry. It is to increase the elastic modulus and tensile strength of rubber, significantly improve the wear resistance and compression performance of rubber, reduce the viscosity of rubber, and save processing energy consumption. 

2.HENGDA-Si69 is suitable for rubber formulations that use hydroxyl fillers in double bond-containing polymers or their blends. 

3.Applicable fillers include silica, 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 diene monomer (EPDM), etc.
