An environmentally friendly and phenol-free pentaerythritol diphosphite antioxidant, with high effective phosphorus content, no free phenol residue, more in line with environmental protection requirements, pentaerythritol spiral ring structure, and good heat resistance. It can be used in PVC environmental stabilizers, lubricating oils, polyurethanes, (un)saturated resins, polyester polyols, coatings, and other polymer materials to protect the color and transparency of polymers during synthesis. It can also improve the later thermal stability of the polymer. It is recommended to use it together with hindered phenolic antioxidants and UV absorbers for better results.
Suggested dosage: 0.1–2.0%.
