Antioxidant weston DPP

Introduction

Antioxidant weston DPP chemical name Diphenyl Phosphite, is a dialkyl phosphite that can be used to improve the color of unsaturated polyesters.

Application:

Antioxidant weston dpp is not only an excellent catalyst for esterification but also provides superior color protection performance in the polymer synthesis process.
Weston DPP is a phosphite processing stabilizer, it can be widely applied as a non-stain & non-discoloration stabilizer and antioxidant due to its more rapid decomposition capacity of peroxide. With elastomers, adhesives, engineering plastics, synthetic resins, mineral oil and other organic matrices, it can improve the color and brightness of the products. Antioxidant DPP also can improve the plate-out performance of PVC products.
