Application

Dioctyldiphenylamine is used in all kinds of special cable, rubber shoes, rubber floor, sponge, triangle belt, synchronization belt, sealing belt, rubber roller and other products. Dioctyldiphenylamine can be used as an antioxidant of polyolefin and lubricating oil, it has a more prominent heat resistance in chloroprene gum, and if used with antioxidant TPPD, the heat resistance is better. It can also reduce the plasticity of unvulcanized chloroprene adhesive and reduce the shrinkage rate during rolling, thus helping to adjust the size of semi-finished products and improve the stability of chloroprene adhesive during storage and transportation. Dioctyldiphenylamine is mainly used to make tires.
