N,N-DIPHENYL-P-PHENYLENEDIAMINE

It can be used as antideteriorant in solid propellant to improve the storage stability of product, and it can be used for those rubbers and latices of natural, styrene-butadiene, acrylonitrile-butadiene,cis 1,4polybutadiene,butyl,butylhedroxyl,cis-1,4-polyisopreneetc, so that to possess them those properties such as good resistance to many times of flexure and chap-resisting , highten the elongating strength , strengthen the defending function to hot-oxygen , ozoneand some harmful metals such as copper , manganese and so on , and do not influence vulcanization of those rubbers. It can beresolved manifold problems existing in the deep-color rubberzproducts while antioxidant H is used together with antioxidant D. Moreover it can be also used as the hot-oxygen stabilizer forthose engineering plastics such as polyethylene, polypropylene,polyamide, polyformaldehyde and etc to improve their imate-resisting performance. The referential dosage is2-0.3%.
