Bis(triethoxysilylpropyl) disulfide Usage And Synthesis

Application	Footwear - Abrasion resistance - Cutting and chunking resistance - Flex life improvement Rolls - Abrasion resistance - Aging resistance - Processing- Set reduction (better load bearing) - Reduced water swell - Lower hysteresis Mechanical Molded Goods - Increased modulus - Better heat aging - Compression set reduction - Dynamic property improvement - Reduced swell to polar liquids - Filler substitution (non-black for black) Hose - Improved abrasion on cover - Better heat aging - Increased modulus - Lower compression set - Improved adhesion to reinforcing elements Solid Tires - Improved abrasion - Lower hysteresis - Higher modulus - Improved processing - Possibly better adhesion Tires - Treads for abrasion, hot tear - Carcass for adhesion and/or filler substitution - Breaker (belt) stocks for adhesion Belts Flat Belts - Increased abrasion - Improved reversion resistance - Reduced cost with clay substitution for black - Improved cord adhesion - Increased flex life and modulus V Belts - Increased modulus - Improved abrasion - Longer flex life - Improved adhesion to reinforcing elements
Chemical Properties	Yellowish clear liquid
