1、Silane Coupling Agent

Silane coupling agents improve the mechanical properties of silica and silicate containing fillers. A chemical bond is formed between the filler and the rubber matrix. The generally used silane coupling agents are bis- (3-triethoxysilylpropyl)tetrasulfane and 3-thio-cyanatopropyl triethoxysilane.
