We are offering zinc oxide.
End applications
rubber industry :
activation : in the curing process for natural rubber and most types of synthetic rubbers, the chemical reactivity of zinc oxide is utilized to activate the organic accelerator. Adequate levels of zinc oxide contribute markedly to chemical reinforcement, scorch control, and resistance to heat-aging and compression fatigue.
Heat stabilization : zinc oxide similarly retards devulcanization of many types of rubber compounds operating at elevated temperatures.
Latex gelation : in the production of latex foam rubber products, zinc oxide is particularly effective in gelation of the foam with sufficient stability.
Pigmentation : through its high brightness, refractive index, and optimum particle size, zinc oxide provides a high degree of whiteness and tinting strength for such rubber products as tire sidewalls, sheeting and surgical gloves.
Reinforcement : zinc oxide provides reinforcement in natural rubber, and in some synthetic elastomers such as polysulfides and chloroprenes. The degree of reinforcement appears to depend upon a combination of the particle size of the oxide, the finest size being the most effective, and the reactivity of the oxide with the rubber. Under such service condition involving rapid flexing or compression, zinc oxide also provides heat conduction to more rapidly dissipate the heat and thereby provides lower operating temperatures. In addition, it imparts heat stabilization by reacting with acidic decomposition products.
Rubber - metal bonding : in the bonding of rubber to brass, zinc oxide reacts with copper oxide on the brass surface to form a tightly adhering zinc-copper salt.
Paint industry :
paints: zinc oxide in organic coatings provides a broad spectrum of properties: optical, chemical, biochemical and physical. Over the past century the paint industry, in its constant development of improved products, has utilized various aspects of those properties to high degree.
