BaodingFST Si69-50E

First Rubber SI-69-50E is a pre-dispersed, 50% active sulfur-containing silane coupling agent based on bis(triethoxysilylpropyl) tetrasulfide (TESPT). It acts as a critical molecular bridge, chemically bonding inorganic silica (SiO₂) fillers to the organic rubber matrix via its ethoxy groups and sulfur chain. This interaction significantly enhances filler dispersion and reinforcement, leading to reduced rolling resistance, improved abrasion resistance, and increased tensile strength in the final vulcanizate. The pre-dispersed masterbatch form ensures dust-free handling and superior compatibility, eliminating moisture absorption issues common with liquid silanes.
