Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) is currently the largest manufacturer of functional specialty chemicals in Taiwan. It has been pursuing and developing products that meet market needs for a long time. After understanding customer needs, it helps customers to develop new products to solve problems and meet their needs.

GY-S-6940 is a bifunctional polysulfide organ silane coupling agent, which is widely used in the rubber and plastic industries to improve the heat generation problem of rubber. For example, adding a sulfur-containing silane coupling agent to rubber tires can reduce tire pressure under high-speed or long-term driving, and the risk of tire blowout due to excessive temperature also can reduce the rolling resistance of tires on the road, thereby reducing fuel consumption and exhaust emissions, achieving the environmental protection concept of energy saving and carbon reduction.
