Chemical Name：Bis (3-triethoxysilypropyl) tetrasulfide
CAS NO.:40372-72-3

It is a multi-purpose silane coupling agent which is used in rubber and plastic industry. It can improve the rubber’s physical and mechanical properties, tensile strength, anti-peel strength, wear-resisting, etc.; Meanwhile it may reduce the material viscosity and enhance workability. It is especially suitable for the vulcanized rubber system which uses silica, silicate and so on. As reinforcing additive. The suitable fillers contain silica, talc powder, clay, mica powder, and pottery clay and so on, and the suitable polymers contain NR, IR, SBR, BR, NBR, EPDM and so on.
