Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) is currently the largest manufacturer of functional specialty chemicals in Taiwan. And develop new products to solve customers’ problems and meet their needs.

GOYENCHEM-HER is a symmetrical aromatic diol chain extender. It has good compatibility with MDI. It is a new type of non-toxic chain extender that can replace traditional MOCA. It is widely used in the Shore hardness range of 90A~60D. Low temperature melting point operation avoids the shortage of rapid crystallization under cooling, improves elasticity, softness, and low shrinkage, and has cut and tear resistance. Its discharge, cut and trim can improve perfection when mixing and granulating.

GOYENCHEM-HER is an indispensable chain extender, especially for fields with high physical requirements.
