Active zinc oxide is white spherical powder, density 5.47g/cm3, melting point of 1800. Do not dissolve in water, soluble in acid, alkali, ammonium chloride and ammonia.
Used:
Active zinc oxide are generally used for rubber industry, it mainly as natural rubber, synthetic rubber and latex activator.Active zinc oxide fine particles was spherical, with a larger surface and, with good dispersion and adsorption, and thus can promote the rubber vulcanization, Activation and reinforcing anti-aging process, improve the tear resistance of rubber resistance, grindability.Also used white latex colorants and fillers, the curing agent in neoprene rubber, plastic industry, light stability, but also for plastic, enamel, paint and other chemical industries.
Packing and storage:
This product is packed with plastic-lined and plastic-coated woven bags, 25kg per bag. This product should be kept from breakage, moisture, pollution and contact with acid.
