• Description: ANTIOXIDANT 168 is a secondary antioxidant with excellent resistance to extraction by water, low volatility and high heat stability. It can effectively decompose hydroperoxides produced during the processing of polymeric materials. ANTIOXIDANT 168 usually not used alone, is compounded with hindered phenolic primary antioxidants such as 1010 to improve thermostability of polymer during the processing. There are over ten kinds of blends of 168 with phenolic antioxidants, widely use in the polymer materials such as PE, PP, PA, PC, ABS and so on.
• Uses: Tris(2,4-tert-butylphenyl) Phosphite is an intermediate in the synthesis of Tris(2,4-di-tert-butylphenyl)phosphate (T884500), a processing stabilizer for polymers. This product is an excellent Antioxidant wnameely applied to polyethylene, polypropylene, polyoxymethylene, ABS resin, PS resin, PVC, engineering plastics, binding agent, rubber, petroleum etc. for product polymerization.
