Product name: Anti-aging agent TPPD
Chemical name: N-N-phenyl-p-phenylenediamine
Molecular weight: 338.4
Molecular formula: C19H18N2O2S
Properties: gray powder, non-toxic, relative density 1.32, melting point not less than 135°C, soluble in acetone, slightly soluble in dichloroethane, benzene, hot water and hot alkali solution, insoluble in gasoline and water, stable storage.
Uses: Anti-aging agent for neoprene, natural rubber, butadiene rubber, styrene butadiene rubber and its latex. It has good protection against ozone and oxygen aging, and can also inhibit copper and manganese damage. It is especially suitable for protecting neoprene from aging Explained during the period
The damaging effect of the released chlorine on the fiber material. This product is easy to disperse and can be directly added to rubber, or it can be made into water dispersion and added to latex. When this product is used in chloroprene rubber, if it is used together with antioxidant ODA, it has the best heat resistance. It can also reduce the plasticity of unvulcanized chloroprene rubber and reduce the shrinkage rate during calendering, thus helping to adjust the size of the semi-finished product. This product is mainly used in the manufacture of tapes, electrical insulation products and light-colored industrial products. The general dosage in neoprene is 1-2 parts.
