Properties: This product is macromolecular antioxidant, no pollution, no coloring, low volatility, water extraction resistance. It can be used for polyethylene, polyoxymethylene, ABS resin, especially for polypropylene. This product can be used in polypropylene resin with auxiliary antioxidant DLTDP, which can significantly improve its thermal stability. It is one of the most excellent phenolic antioxidants at present. With the restriction of environmental protection laws and regulations in foreign developed areas, the original tin products will gradually transit to Wuxi products.

 

Usage: This product is a kind of multi-component hindered phenolic antioxidant, which has good compatibility with most polymers. It can prevent the discoloration caused by light and heat. Widely used in PE, PP, PS, polyamide, POM, ABS resin, PVC, synthetic rubber and other polymer materials. It is also used to prevent thermal oxidative aging of grease and coatings.

 

Reference dosage: the general dosage is 0.1% ～ 0.5%,
