Superiority

CY-69 Bis[3-(triethoxysilyl)propyl]tetrasulfide reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under formation of covalent chemical bonds. This imparts better tensile strength, higher module, reduced compression set, increased abrasion resistance and optimized dynamic properties. It is used in many applications where white fillers containing silanol groups are involved and optimum technical properties are required.

1. Tires: An excellent reinforcing agent in tires to reduce heat built-up, reduce rolling resistance and improve the tires´ wet grip. 
2. Shoe Soles: Generally applicable silane for improving abrasion resistance of sole compounds containing precipitated silica.
3. Mechanical Rubber Goods: General use silane for achieving good dynamic properties, low compression set and high abrasion resistance in mixtures containing white fillers.
4. Adhesives and sealants: An excellent adhesion promoter to glass, aluminum, steel and other inorganic surface in polysulfide, nitrile and other rubber adhesives, sealants and coatings.

Applications

Main Application Industries: Silicone Rubber; Tyre; Rubber

Application: CY-619 is a kind of silane coupling agent with multiple functional groups successfully used in rubber industry to improve modulus and tensile strength of rubber, to reduce the compound viscosity and save process energy consumption. It is especially applicable for polymers with double bond or rubber formulation with hydroxyl fillers.

Suitable for sulfur rubber and can improve the crosslinking stability, tear resistance, shear resistance, water resistance and reduce the compression deformation.

The suitable rubber include natural rubber (NR), Butadiene styrene rubber (SBR), Isoprene rubber (IR), Butadiene rubber (BR), Acrylonitrile butadiene rubber (NBR), Ethylene propylene diene rubber (EPDM), etc.

The suitable inorganic fillers include carbon black, white carbon black, glass fiber, talc, mica, fly ash and clay ect.

It is applicable for rubber, tire (tread, tire body and the tire wall), and solid rubber tire roller surface. The conveyor belt surface, steel brush wire bonding, cable (insulation layer and coated layer) shoes (warrior shoes, marathon shoes and tennis shoes)
