The chemical formula of calcium stearate is C36H70CaO4, CAS number 1592-23-0. It is usually a white fine powder, odorless and fluffy in texture. It is insoluble in water, ethanol, ether and other solvents, and can only be dispersed in hot water. It has stable chemical properties, is acid-resistant, alkali-resistant, and high-temperature resistant. It will not decompose until heated above 400°C. It has both lubricity and anti-adhesion properties, and has certain thermal stability. It has good compatibility with polymer materials such as resin and rubber. Industrially, it is mainly used in the field of plastic processing (as heat stabilizer, lubricant and release agent), rubber industry (as rubber softener and release agent); it is also used in coatings and adhesives (as anti-sedimentant, matting agent), food industry (as anti-caking agent), and can also be used in cosmetics (to adjust texture), feed additives (moisture-proof and anti-caking), building materials (water-proof additives) and other fields.
