3-Thiocyanatopropyltriethoxysilane Chemical Properties,Uses,Production

Description

3-Thiocyanatopropyltriethoxysilane is a bifunctional, sulfur-containing organosilane for rubber applications in combination with white fillers containing silanol groups.

In silane industry, it has good features that includes:

  • It can improve reinforcing properties of fillers that contain hydroxyl groups.
  • It can improve physical and mechanical properties of vulcanizates. It can improve tensile strength, tearing strength and abrasive resistance and reduce compression set of vulcanizates. In addition, it can reduce the viscosity and improve the processability of rubber products.
