Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) is a leading manufacturer of specialty chemicals in Asia. We devote ourselves to supplying products and solutions to our customers worldwide to satisfy and expand the market needs.

GY-S-6920 is a sulfur silane coupling agent widely used in the rubber industry. It increases the modulus of elasticity and tensile strength of rubbers and improves abrasion resistance and compressibility. GY-S-6920 bestows rubbers with excellent physical and mechanical properties and reduces viscosity, which leads to higher productivity. If applied to tires, GY-S-6920 decreases the risk of flat tires due to excessively high-temperature caused by high speed or long duration drives. It reduces rolling resistance, gasoline consumption, and CO2 pollution effectively.
