GY-PUA-70 Anti-Hydrolysis Agent

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-PUA-70 is a carbodiimide-based hydrolysis agent which can initially occur a chemical reaction with hydrolysate ─ carboxylic acid or water to prevent polymer from degradation. It provides end product with improved hydrolysis resistant properties particularly in the environmental conditions such as high-temperature, high-humidity, acidic and alkaline, which prolongs the product life. GY-PUA-70 is ideal for the polymers producing hydrolysate easily; polymers such as polyesters, polyurethane, polyamide, etc.
