Structural formula Antioxidant TPPD
Molecular formula


Molecular weight 338.4
Properties non-toxic, Relative Density 1.32, Melting pointisn't less than 135ºC,
Uses antioxidant of chloroprene rubber, natural rubber, polybutadiene rubber, styrene butadiene rubber and latex to prevent harms of ozone, oxygen and aging well, can also suppress copper and manganese harms, especially for protection chloroprene rubber from the age damaging effects of release chlorine on the fiber material. This product is distributed directly by adding rubbers, also made by adding latex dispersion. This product is used for chloroprene rubber, work with ODA can offer the best heat resistance, and also reduce the plasticity of unvulcanized chloroprene rubber and the shrinkage during rolling, thus helping to adjust the size of semi-finished products. This product is mainly used to produce plastic sheets, electrical insulation products, and light colored industrial products, Dosage in neoprene is 1-2 portions.
