| Use | suitable for vulcanized rubber system with silica or silicate as reinforcing agent is a multifunctional group which has been successfully applied in rubber industry silicone coupling agent. Its role is to improve the elastic modulus and tensile strength of rubber, significantly improve the wear resistance and compression properties of rubber, while reducing the viscosity of rubber, saving processing energy consumption. It is most suitable for rubber formulations employing hydroxyl-containing fillers in double-bond-containing polymers or blends thereof. Suitable fillers include white carbon fume, silicates, chalk, etc.; Suitable 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. Compared with 40372-72-3, this product can provide more reliable scorch safety because of its lower activity of dithiane functional groups. |
