Description and Uses

4,4'-Diphenylisopropyl diphenylamine (Antioxidant HS-911) is a kind of high-efficient nontoxic Antioxidant to replace D, A, RD and so on which are carcinogenic. HS-911 can be used in NR, IIR, SBR, NBR, BR, CR and their blend, and is especially efficient in protecting CR from thermal aging. It can also be used in plastic industry. HS-911 not only can protect vulcanized rubber from thermal aging, light aging, ozone aging and damage caused by repeating deformation, but also has a passivating effect on heavy metal and transition metal.

Because of its light contamination, HS-911 can be used in insulative and protective rubber sheeting for color wires and cables as well as common color rubber products in place of Antioxidant 264, SP, 2264, MB, DNP, etc, to greatly reduce the production cost. In carbon black rubber, it has oxidation resistance of amine type, and will not pollute products. HS-911 can be exclusively used or used together with other Antioxidant . Normal dosage in rubber is 2-3 phr.
