tyre grade active zinc oxide

tyre grade active zinc oxide Uses: vulcanization accelerator , reinforcing agent , UV stabilizer, fast-dry ink, , desulfurizeractive zinc oxide is a major rubber reinforcing agent or cable, so that rubber has good corrosion resistance, tear resistance and flexibility. The vulcanized natural rubber is also used as activator, white rubber, colorants and fillers, chloroprene rubber curing agent. Is widely used in the footwear industry, chemical industry, light industry, pharmaceutical products, production, also to create a transparent rubber and food products essential to rubber active agent Structure of spherical or globular shape chain Zinc oxide (ZnO),% 95 98 105 °C volatile mass fraction,% ≤ 0.5 Water-soluble matter,% ≤ 0.5 Loss on ignition,% ≤ 1 4 Hydrochloric acid insoluble substance,% ≤ 0.04 Lead oxide (Pb),% ≤ 0.01 Manganese oxide (Mn),% ≤ 0.001 Copper oxide (Cu),% ≤ 0.001 Cadmium oxide (Cd),% ≤ 0.005 Fineness (45um test sieve),% ≤ 0.1 Specific surface area m2 / g, ≤ 40
