Crosile®75 (Bis(3-triethoxysilylpropyl)disulfide) TESPD is a bifunction polysulfidic organosilane and has been widely in the rubber industry. Crosile®75 TESPD is used to improve the reinforcing capability of fillers with silanol group on the their surface,and also as an integral part of curing systems to improve cross-linking network properties. Compared to the Crosile®69 (Bis(3-triethoxysilylpropyl)tetrasulfide), Crosile®75 has a higher temperature stability and therefore allows higher mixing temperatures. Crosile®75 imparts greater tensile strength, higher module, reduced compression set, increased abrasion. resistance and optimized dynamic properties.
Crosile®75C Silane coupling agent carbon black can improve the physical and mechanical properties of rubber, greatly improve the tensile strength, tear strength, wear resistance, reduce the permanent deformation and viscosity of the wool rubber, and improve the processing performance.
