3-Thiocyanatopropyltriethoxysilane
3-Thiocyanopropyltriethoxysilane is a sulfursilane that enhances the abrasion resistance, elasticity, and tear strength of rubber products, while reducing compression set. It also improves the dispersion of fillers in rubber and strengthens the interaction between fillers and rubber. With its light color, it is particularly ideal for light-colored rubber products, such as those used in the footwear industry. This silane provides similar benefits to other sulfursilanes.
Key Benefits:
✔ Improves rubber properties – Enhances abrasion resistance, elasticity, and tear strength.
✔ Reduces compression set – Increases rubber durability and performance.
✔ Filler dispersion – Optimizes filler distribution and rubber-filler interaction.
✔ Ideal for light-colored rubber – Perfect for footwear and other light-colored rubber products.
