[Uses]

TRIS(NONYLPHENYL) PHOSPHITE is a non-polluting, heat-resistant, antioxidant, and anti-aging agent used as a stabilizer and antioxidant in natural rubber, synthetic rubber, latex, and plastics. It is suitable for rubber and plastic elastomers such as SBS, TPR, IPS, PS, SBR, BR, PVC, PE, PP, and ABS. It exhibits high thermo-oxidative stability, does not discolor during processing and use, and is particularly suitable as a non-discoloring stabilizer. It has no effect on product color and is widely used in white and brightly colored products. It can improve the heat resistance and antioxidant properties of rubber and plastic products, prevent resinification during polymer manufacturing and storage, inhibit gel formation and viscosity increase, and prevent thermo-oxidative aging and yellowing of rubber and plastic products.
