Zinc oxide Molecular formula: ZnO Molecular weight: 81.38 white hexagonal crystals or powder, odorless, non-toxic and fine.
This product is soluble in NaOH, NHCI, insoluble in water, ethanol and ammonia, is a gender-oxide, a UV-absorbing function.
Used: Extensive use of zinc oxide in rubber industry, rubber products can increase the flexibility and abrasion resistance, zinc oxide white pigment in paint to do, but also can play inhibit fungi, mildew, anti-pink, and improve durability of effect. In addition, zinc oxide is also a variety of chemical raw materials for the production of intermediates, and for ceramics and glass and textile industries, such as reaction with organic acid used as rubber softeners zinc soap is made for synthesis of zinc sulfide-based materials, intermediate Ying.
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.
