Sulfur Silane Coupling Agent Crosile for Rubber Type and Filler Modified

A comparative study of α- and γ-functional silane coupling agents in silica-filled SBR vulcanized with conventional sulfur systems shows that the effects of silanes on vulcanization kinetics and their coupling effects depend on their structure and location. Rubber reactive groups. All tested silanes containing mercapto or sulfide functional groups resulted in improvements in tensile properties and affected the cure kinetics of the systems used.

sulfur silane application

Crosile®69, Crosile®75 is a multifunctional silane coupling agent, which has been successfully used in the rubber industry to improve the modulus and tensile strength of the rubber, reduce the viscosity of the rubber compound, and save the energy consumption of the process. Particularly suitable for double-bonded polymers or rubber formulations containing hydroxyl-containing fillers. Suitable fillers include silica, silicates, clays, and the like.

Crosile®264 is a sulfur silane, which can improve the wear resistance, elasticity and tear strength of rubber products, reduce the compression set, and also improve the dispersion of fillers in rubber and the interaction between fillers and rubber.

Crosile®1891 is mainly used in combination with inorganic fillers such as carbon black and Si 2, and has the functions of activation, coupling, cross-linking and reinforcement in polymers such as rubber and silicone rubber

Crosile®189 has a special effect as a metal surface rust inhibitor. When used to treat the surface of metals such as gold, silver, and copper, it can improve the corrosion resistance and oxidation resistance of the surface. And can enhance the adhesion to the resin polymer. In the rubber industry, it is often used to process inorganic fillers such as silica, glass fiber, and mica.
