Product Details

Formula:

C10H21NO3SSi

CAS Number:

34708-08-2

Also Known As:

3-(Triethoxysilyl)propyl thiocyanate; Thiocyanic acid, 3-(triethoxysilyl)propyl ester

applications:

Thiocyanatopropyltriethoxysilane is used extensively in rubber applications, particularly with "white fillers" (like silica) that contain silanol groups. It improves the reinforcing properties of these fillers in rubber compounds. It enhances the physical and mechanical properties of vulcanized rubber, including tensile strength, tear strength, and abrasion resistance. It also reduces compression set, and improves the processability of rubber compounds.
