Overview of Zinc Stearate

Zinc stearate is an organic substance with a chemical formula of C36H70O4Zn. It is a white powder and is insoluble in water. Mainly used as lubricant and release agent for styrene resin, phenolic resin and amino resin. At the same time, it also has the function of vulcanization activator and softener in rubber.

Zinc stearate is a "zinc soap" widely used in industry

Zinc stearate is a "zinc soap" widely used in industry. In this case, the soap in its formal meaning, the metal salt uses a fatty acid: in this case stearic acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether, and soluble in aromatic hydrocarbons (such as benzene) and chlorinated hydrocarbons when heated. It is the strongest release agent among all metal soaps. It contains no electrolytes and has a hydrophobic effect. Its main application area is in the plastics and rubber industries. It is used as a release agent and lubricant and can be easily added.

Zinc carboxylates, such as alkaline zinc acetate, use complex formulations instead of simple zinc dicarboxylates. In contrast, the molecular formula of most zinc carboxylates is Zn4O(O2CR)6, which consists of a Zn4O6+ core and a carboxylate ligand that spans the edges.

It is widely used as a release agent for the production of many objects: rubber, polyurethane, polyester processing systems, powder metallurgy. These applications take advantage of their "non-stick" characteristics. In cosmetics, zinc stearate is a lubricant and thickener used to improve texture.

It is an "activator" that accelerates the sulfur vulcanization of rubber. As discovered in the early stages of vulcanization, zinc has a beneficial effect on the reaction of sulfur with polyolefins. Stearate is a form of zinc that is highly soluble in non-polar media of polyolefins.

Being lipophilic, it is used as a phase transfer catalyst to saponify fat.

Application of zinc stearate

Zinc base stearate is widely used in lubricants, stabilizers, decolorants and thickeners. It is used for the demoulding process of polystyrene resin, phenolic resin and amino resin. It is an excellent additive for rubber and plastics, as well as a surfactant and softener.
