CAS No. : 80584-86-7
Molecular weight: ~2100
Application Instructions
A high-molecular-weight, high-phosphorus content polymeric phosphite ester antioxidant, suitable for multi-purpose polymers, including PVC, ABS, polyurethane, polycarbonate and coatings. It can enhance the thermal stability and long-term stability of products during processing and application. As an auxiliary antioxidant and chelating agent, it can be used in rigid or flexible PVC products, enabling PVC to maintain a brighter and more lasting color and enhancing its thermal stability. When applied in polyurethane materials, it has a significant inhibitory effect on phenolic yellowing and NOX yellowing, and improves their thermal stability and long-term stability. Suggested addition amount: 0.1-2.0%
