A polymeric phosphite antioxidant with high molecular weight and high phosphorus content, suitable for multi-purpose polymers, including PVC, ABS, polyurethane, polycarbonate and coatings, can improve the thermal stability and stability of products during processing and application, and long-term stability. Used as an auxiliary antioxidant and chelating agent in hard or soft PVC products, it can keep PVC brighter and longer in color and can improve its thermal stability. Applied in polyurethane materials, it has a significant inhibitory effect on phenol yellow and gas fumigation (NOX) yellowing and improves its thermal stability and long-term stability.
Suggested addition amount: 0.1–2.0%.
