Metallic stearates are compounds of long-chain fatty acids with metals of different valencies. The most important metallic stearates, in terms of quantity, are the metallic stearates of aluminium, calcium, magnesium and zinc. The main advantage is their manifold range of use.
Metallic stearates have been utilized in the rubber industry a long time. The primary functions of metallic stearates are their ability to prevent rubber from sticking to the mold as well as to itself. The compounder has found numerous ways to take advantage of the physical and chemical properties of metal stearates.
Metallic stearates are defined as the metal salts of an 18-carbon chain fatty acid, known as stearic acid. They are commonly produced by the reaction between a stearic acid and metal salts, such as metal oxides, metal hydroxides, metal sulfate, and metal chloride.
