3-Thiocyanopropyltriethoxysilane

Product Overview

3-Thiocyanopropyltriethoxysilane is a specialized organosilicon compound designed to function as a highly effective coupling agent within the rubber and polymer industries. This chemical serves as a critical bridge between inorganic fillers and organic polymer matrices, facilitating superior bonding and interaction at the molecular level. As a direct equivalent to established industry standards such as Evonik Degussa Si 264, this product offers manufacturers a reliable solution for enhancing the mechanical properties of compounded rubber materials.

Our manufacturing process ensures high purity and consistent quality, making it an ideal choice for demanding applications where performance stability is paramount. The compound features a reactive thiocyanato group and hydrolyzable ethoxy groups, allowing it to interact effectively with both silica-based fillers and various unsaturated polymer chains. This dual functionality is essential for modern rubber compounding, particularly in the production of high-performance tires and mechanical rubber goods.

Technical Specifications

Industrial Applications

This silane coupling agent is extensively used to increase the reinforcing properties of hydroxyl-based fillers in all double-bond unsaturated polymers. The applicable fillers include silica, talc, clay, mica powder, and china clay. It is compatible with a wide range of polymer systems, including Natural Rubber (NR), Isoprene Rubber (IR), Styrene-Butadiene Rubber (SBR), Butadiene Rubber (BR), Nitrile Rubber (NBR), and Ethylene Propylene Diene Monomer (EPDM).

In the tire manufacturing industry, this product plays a vital role in silica-reinforced green tires, contributing to lower rolling resistance and improved fuel efficiency without compromising traction. Beyond tires, it is utilized in various mechanical rubber goods where durability and structural integrity are critical. The ability to modify the surface energy of fillers ensures better dispersion within the rubber matrix, leading to more homogeneous compound properties.

Performance Benefits

• Significantly improves tensile strength and tear strength of the final rubber product.
• Enhances wear resistance, extending the service life of rubber components.
• Reduces permanent deformation, ensuring better shape retention under stress.
• Lowers the viscosity of the rubber compound, improving processing performance and mixing efficiency.
• Optimizes the interaction between silica fillers and polymer chains for superior reinforcement.
• Acts as a reliable drop-in replacement for legacy products like Degussa Si 264.
