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.
Zinc Borate - The Chemical Company
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 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 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.

Chemicals Used to Soften Rubber | Home Guides | SF Gate
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.
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.

Zinc distearate is mainly used in the EU in the polymers industry as a stabilizer component (e.g. in PVC stabilisers), lubricant, mold release agent and dusting agent for rubber (55 %). Zinc distearate is further used in the paints, lacquers and varnishing industry as a sanding and flatting agent (18%), in the: building industry as a

The function of SA as a softener and a filler dispersing agent within rubber compounds is examined. of chemical blowing agents, an eco processing aid and a soluble-zinc-soap-based
The determination of zinc oxide in rubber vulcanizates by x
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
