ZN2267 Zinc Stearate Powder (CAS No. 557-05-1)

Description of Zinc Stearate Powder

Zinc stearate is a zinc soap that is widely utilised in industry. In this context, soap refers to the metal salt of a fatty acid. It appears as a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether, but becomes soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the most effective form release agent among metal soaps. It contains no electrolyte and exhibits hydrophobic properties. Its primary fields of application are in the plastics and rubber industries, where it is employed as an easily incorporated release and lubricating agent.
