A phenol-free and environmentally friendly trialkyl phosphite antioxidant that does not contain phenol, octylphenol, nonylphenol, and bisphenol A. It can be widely used in PVC, LLDPE, HDPE, ABS, SBS, polyurethane, and other polymers, providing excellent thermal stability and color stability. As an efficient auxiliary stabilizer and chelating agent used in PVC materials (such as PVC stabilizer, PVC sheet/shaped material, PVC floor, etc.), it can effectively improve its processing thermal stability and light stability, and keep the color of the product stable. and transparency. It can also be used in various polymers such as SBR, NBR, SBS, and polyurethane inks to improve the heat resistance of products.
Suggested dosage: 0.1-2.0%.
