antioxidant 168 is an excellent phosphite antioxidant with white powder appearance, 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, and can effectively decompose the hydroperoxide produced during the thermal processing of polymeric materials. It has good synergistic effect in 1010 and 1076 with hindered amine antioxidants and can improve the stability of polymeric materials during thermal processing. There are more than a dozen preparations compounded with phenolic antioxidants, which are widely used in polyolefins (such as polyethylene, polypropylene) and olefin copolymers, polyamide, polycarbonate, PS resin, PVC, engineering plastics, rubber and petroleum products, ABS resin and other polymer materials. The compound can also be used for adhesives, natural or synthetic adhesive resins, etc. The general dosage is 0.1% ~ 1.0%.
This product can still be fully recovered after soaking in hot water at 90±1 ℃ for 14 hours, and the quality is not affected.
