Application

Antioxidant H can be used as an antioxidant in composite solid propellants to extend the storage period of solid propellants. It can be used in natural, styrene-butadiene, nitrile, butadiene, butyl, butyl hydroxyl, polyisoprene and other rubbers and latex to make them have good resistance to multiple flexures and cracking resistance. It improves the tensile strength and enhances the protection against harmful metals such as copper and manganese, and has no effect on vulcanization. Antioxidant H and antioxidant D can solve various aging problems of dark rubber products. In addition, it is also used as a thermal oxidation stabilizer for polyethylene, polypropylene, polyamide, and polyoxymethylene engineering plastics to improve the weather resistance of the products.
