Product Description:
Antioxidant 168 is an excellent phosphite ester antioxidant, the appearance of white powder, easily soluble in benzene, chloroform, cyclohexane and other organic solvents, slightly soluble in ethanol, acetone, insoluble in water, alcohol and other polar solvents, slightly soluble in esters. Low toxicity, low volatility, high thermal stability, excellent hydrolysis resistance, can effectively decompose the hydroperoxide produced in the process of hot processing polymeric materials. It has good Chemicalbook synergistic effect when used with hindered amine antioxidants 1010 and 1076, and can improve the stability of polymeric materials during hot processing. More than a dozen kinds of preparations have been mixed with phenolic antioxidants, which are widely used in polyolefin (such as polyethylene, polypropylene) and olefin copolymers, polyamides, polycarbonate, PS resin, PVC, engineering plastics, rubber and petroleum products, ABS resin and other polymer materials. The compound can also be used in adhesives, natural or synthetic bonding resins, etc. The general dosage is 0.1% ~ 1.0%.

 

Application: 
The product is a low volatile organic synthesis antioxidant inhibitor, widely used in the synthesis and processing of polypropylene, polyethylene, ABS, polycarbonate fiber and polyester resin and other plastics.
