Antioxidant DPD, wetson 600

Introduction

Antioxidant DPD, weston 600 chemical name Diisodecyl Pentaerythritol Diphosphite is a No free phenol residue, environmentally friendly phosphite antioxidant.

 

Application:

Antioxidant dpd is mainly can be applied in PVC as an environmental-friendly stabilizer and it can improve the transparency and temperature resistance properties of PVC products. It doesn’t contain any free phenol and the phenolic product isn’t generated after hydrolysis or degradation. It is the phosphite antioxidant which has not have phenol completely.
DPD can be used in polymers such as unsaturated resins, saturated resins, polyester polyol, epoxy resins etc. It can protect the color during the polymer synthetic process and improve the heat stability of the polymer in the latter period of the reaction.
