Product: Zinc Oxide (Zinc White) 1. CAS No.: ********2 2. Applications: Rubber manufacture Zinc oxide and stearic acid are ingredients in the commercial manufacture of rubber goods. A mixture of these two compounds allows a quicker and more controllable rubber cure. ZnO is also an important additive to the rubber of car tires. Vulcanization catalysts are derived from zinc oxide, and it considerably improves the thermal conductivity, which is crucial to dissipate the heat produced by the deformation when the tire rolls. ZnO additive also protect rubber from fungi (see medical applications) and UV light. Concrete industry Zinc oxide is widely used for concrete manufacturing. Addition of ZnO improves the processing time and the resistance of concrete against water. Food additive Zinc oxide is added to many food products, e. G., breakfast cereals, as a source of zinc, a necessary nutrient. Some prepackaged foods also include trace amounts of ZnO even if it is not intended as a nutrient. Pigment Zinc white is used as a pigment in paints and is more opaque than lithopone, but less opaque than titanium dioxide. It is also used in coatings for paper. Chinese white is a special grade of zinc white used in artists\**9; pigments. It is also a main ingredient of mineral makeup. Besides it also widely used in Coatings, Medical, Cigarette filters etc. Index Item Index Type I Type II Super Grade Grade1 Qualified Grade Super Grade Grade1 Qualified Grade Zinc oxide %≥ *9.*0 *9.*0 *9.*0 *9.*0 *9.*0 *9.*0 Metallic metals (as Zn) %≤ None None 0.**8 None None 0.**8 Lead oxide (as pb) %≤ 0.**7 0.*5 0.*4 - - - Manganic oxide (as Mn) %≤ 0.***1 0.***1 0.***3 - - - Copper oxide (as Cu) %≤ 0.***2 0.***4 0.***7 - - - Insolubles in HCL solution%≤ 0.**6 0.**8 0.*5 - - - Losses on ignition %≤ 0.2 0.2 0.2 - - - Screening residues (through *5Î&frac*4;m mesh) %≤ 0.*0 0.*5 0.*0 0.*0 0.*5 0.*0 Soluble matters in Water %≤ 0.*0 0.
