TESPT Organosilane Coupling Agent

Silane coupling agents have been used in the rubber industry since the 1950s. Their use started in the shoe sole Industry where they enabled rubber to have greater abrasion resistance and thus better wear. [Pg.215]

for the hydrated precipitated silica to be effective in reducing the rolling resistance in a tire tread, it must be used with an organosilane. The most common organosilane used today as a rubber compounding ingredient for use with silica is TESPT (bis-[3-(triethoxysilyl)propyl] tetrasulfide). [Pg.215]

Several new standard ASTM test methods have been developed to characterize and control the quality of TESPT. These methods are listed below. [Pg.215]

ASTM D6844 Purity by HPLC Method ASTM D6740 Ignition Loss Test for Residue [Pg.215]

ASTM D6844 Characterization by High-Performance Liquid Chromatography [Pg.216]
