Antioxidant for neoprene rubber, natural rubber, butadiene rubber, styrene butadiene rubber and latex has a good protective effect on ozone and oxygen aging, and can also inhibit copper damage and manganese damage, especially suitable for preventing the destruction of fiber materials by chlorine released during the aging of neoprene rubber. This product is easy to disperse, can be directly added to rubber, can also be made into water dispersion to add latex. When this product is used in neoprene rubber, if it is used with antioxidant ODA, the heat resistance is the best, it can also reduce the plasticity of unvulcanized neoprene rubber, so that the shrinkage rate is reduced when calending, thus helping to adjust the size of semi-finished products. This product is mainly used in the manufacture of adhesive cloth, electrical insulation products and light colored industrial products, in the general dosage of neoprene rubber is 1-2 copies.
