GOYENCHEM-HQEE Chain Extender CAS NO. 104-38-1

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.

GOYENCHEM-HQEE is a symmetrical aromatic diol chain extender, a new type of non-toxic chain extender that replaces traditional MOCA. It is commonly used in PUR (CPU, TPU, MPU) of MDI, Polyol Polyurethane, and various elastomers. It features strong hardness, heat resistance, high tensile strength, and increased resilience. It also improved the intactness of discharging and cutting during mixing granulation.

GOYENCHEM-HQEE improves the cell resilience of foam products, especially for applications that require demanded physical properties.
