Applications

YIPHOS® 2013 is a phenol-free, eco-friendly trialkyl phosphite antioxidant. It is a suitable substitute for antioxidant TNPP with low volatility and good hydrolysis resistance. It can be widely used in polymers such as PVC, rubber, plastics, and oil products. YIPHOS® 2013 can effectively improve the thermal stability and anti-fading((NOx) performance of polyurethane foam. As an
efficient auxiliary stabilizer and chelating agent used in soft/hard PVC materials, it effectively improves its processing thermal stability and light stability, and maintains the color stability and
transparency of the product. YIPHOS® 2013 is a highly efficient antioxidant for rubber materials such as ABS, SBS, SIS, and SEBS.
