GOYENCHEMUV-709 Highly Effective Anti-UV/Anti-Yellowing Agent

Description

Intro

Polyolefin (e.g. PP, PE), olefin copolymer (e.g. EVA), elastomers (e.g. PU, TPU) are broadly used in various sectors; PP, PE, EVA are especially and largely made into films used in wide range of industries as they show great weather resistance and stretchability. However, these materials typically face the yellowing and degradation problems which especially agricultural films would frequently encounter resulted from sunlight, heat, oxygen, and even sulfide which is commonly used in agriculture which accelerates the degradation.

Manufactured by using nanotechnology, GOYENCHEMUV-709 Highly Effective Anti-UV/Anti-Yellowing Agent is developed by GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) and is designed mainly for polyolefin and olefin copolymer which are the major materials to various films, as well as for elastomers. It provides polymers with outstanding anti-UV effect and long-term heat stability, as it effectively reduces the yellowing of high polymers.

GOYENCHEMUV-709 is particularly suitable for agricultural films as it exhibits great anti-sulfide performance. With low volatility, no migration, and excellent high polymer compatibility which provides great processibility to polymers, GOYENCHEMUV-709 can be used in polyolefin, olefin copolymer, polyacetals, polyamides, polyurethane, etc., and now has been an appointed product to numerous film manufacturers.
