説明
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.

使用
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.

工業用途
This product is one of the few kinds of antioxidant, which is non-toxic, tasteless, light colored. The anti- oxygen effect is similar America in Uniroyal. It is widely used in various kinds of elastomers. It can be used in polyethylene, polypropylene, polyvinyl chloride and other color master batch. It can also be used as antioxidant in polyurethane foam, rubber wire, cable, food package and adhesive, especially in neoprene colorful cable's jacket for its excellent resistance to heat, light, and aging. In polyether this product can be used as light-resistant and anti-aging antioxidant, also as antioxidant for lubricating oil.It is especially effective to be used in neoprene acrylate rubber, polyether polyalcohol for its resistance to aging caused by high temperature and light. When used together with sulfur-contained antioxidant, it has operational effect.
