Papua New Guinea Rubber active zinc oxide

White crystal or powder, belonging to the hexagonal crystal system. Odorless, non-toxic, no sand, fine quality. Density 5.606g/cm3, refractive index 2.0041,1800 C sublimation. The tinting strength is 2 times that of basic lead carbonate, and the hiding power is half of that of titanium dioxide and zinc sulfide. Insoluble in water and ethanol, soluble in acid, sodium hydroxide, ammonium chloride, is an amphoteric oxide. It is yellow when heated at high temperature and returns to white after cooling. In the humid air can absorb carbon dioxide and moisture gradually become basic zinc carbonate. It can also be reduced to zinc metal by carbon or carbon monoxide. There is excess zinc in the zinc oxide lattice, the initial ionization energy of zinc is relatively low, easy to lose electrons, and zinc oxide electron mobility is much larger than the hole mobility, can be regarded as n-type semiconductor.

There is excess zinc in the zinc oxide lattice, the initial ionization energy of zinc is relatively low, easy to lose electrons, and zinc oxide electron mobility is much larger than the hole mobility, can be regarded as n-type semiconductor.

Use:Used for paint pigments and rubber fillers, medicine used to make ointment, zinc paste, adhesive paste, etc. It is mainly used in rubber or cable industry as reinforcing agent and active agent, also as coloring agent and filler of white glue, used as vulcanizing agent in chloroprene rubber, as white pigment, rubber vulcanization active agent, reinforcing agent, organic synthesis catalyst, desulfurizer, etc.

PackagingComposite paper bag, lined with plastic film bag, net weight 25kg.

Storage: Sealed and stored in a cool, ventilated warehouse. Keep away from fire and heat source. Should be stored separately from the oxidant, do not mix storage. The storage area should be equipped with suitable materials to contain the leakage.

Safety and toxicity: Please refer to the relevant product safety data (MSDS).
