we offer Rubber Zinc Oxide. Product name: Rubber zinc oxide Product catalogue: zinc oxide Product introduction: Rubber zinc oxide is multifunctional rubber ingredients mainly used as vulcanizing activator simultaneous reinforcing agent of natural gum, rubber polymer and rubber latex, the colorant and extender of the white size, and curing ingredient of the chloroprene rubber. Basic property: Molecular formula:Zno Molecular weight:81.39 White or fine slight yellow powder, specific gravity 5.5－6.5gcm3, specific surface 8 m2g, granularity 0.15－0.7μm, refraction index 1.95－2.05, the specific heat 0.0915cg℃ at 20℃, meltingpoint 1973℃, it has the phenomenon of evaporation at 1000℃. Chemical property: ①zinc oxide can be restore to the original state by carbon, carbon monoxide and hydrogen at high temperature. ②Zinc oxide is an amphoteric-oxide, which is slight soluble or insoluble in water. It generate relevant arsoniumsalt after reaction with acid, Zn(OH)2 after reaction with alkali and basic zinc carbonate reaction with carbon dioxide and other acid gases. Execution standard: enterprise standard: HHXPQB—YHX(XJ)—2005 Application: Rubber zinc oxide is multifunctional rubber ingredients mainly used as vulcanizing activator simultaneous reinforcing agent of natural gum, rubber polymer and rubber latex, the colorant and extender of the white size, and curing ingredient of the chloroprene rubber. Package, transport, stockpile: Polywoven bags with polythylene film bags inside or waterproofing paper bags, net weight: 50kgbag, dimension: 580 × (1100-1250)mm. It should have covering during the transportation to prevent rain and damp. Keep away from Alkalis and acid during transportation. It should stored in dry and ventilated place. It is strictly prohibited to contact with alkalis.
