    What is the role of zinc oxide in rubber formulations

    First, activate the entire curing system. Zinc oxide and stearic acid together form zinc soap, improve the solubility of zinc oxide in the compound, and with the accelerator to form a complex, this complex is particularly lively, it reacts with sulfur to produce a very strong vulcanizing agent.

    TCC’s zinc borate is a low toxicity, white crystalline, inorganic compound primarily used as a flame retardant and smoke suppressant in plastics and cellulose fibers, paper, rubbers and textiles. It is also used in paints, adhesives and pigments. As a flame retardant, zinc borate can replace antimony trioxide as a synergist in both halogen-based and halogen-free systems. TCC’s zinc borate

    Zinc Oxide – Properties and Applications for Industrial

    Applications of Zinc Oxide for Rubber Industry Rubber products represent the largest market for Zinc Oxide. ZnO is a widely used compound in rubber industry due to the excellent properties it shows as an activator for vulcanization of rubber. Vulcanization is a chemical process for converting natural rubber into a more durable material.

    Rubber Compounding

    Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage.

  • sulfur vulcanization

    Sulfur vulcanization

    Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators.

    Since the 1800s, the process of curing rubber for use in various industries has sparked many developments in curing agents. The first chemical used to cure rubber was sulfur.

  • zinc stearate

    Zinc stearate

    It is widely used as a release agent for the production of many kinds of objects: rubber, polyurethane, polyester processing system, powder metallurgy. These applications exploit its "non-stick" properties. In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture.

    Application to typical accelerated rubber vulcanizates has shown that the rate of zinc oxide disappearance was independent of the amount and type of reinforcing filler. It was found also to be independent of the degree of crosslinking despite the known dependence of high level crosslink formation on the presence of zinc oxide in this type of
