(25448-25-3) Triisodecyl phosphite
Product Description
A phenol-free and environmentally friendly trialkyl phosphite antioxidant. It is suitable for a variety of polymers, including polyurethane coatings, polyolefins, ABS, PVC, PET and lubricating oils, etc., and can provide good color improvement and thermal stability in processing and post-application. As a high-efficiency auxiliary stabilizer and chelating agent, it can be used in hard and soft PVC materials to provide brighter and more uniform colors, and improve the transparency and thermal stability of products. Used in polyurethane foam, it can provide oxidation protection and reduce the risk of foam core burning and burning, and has good anti-phenol yellowing and anti-gas fumigation (NOX) yellowing effects.
Suggested dosage: 0.1–2.0%.
