Calcium stearate, a physiologically safe compound, has gained significant importance in various industries. It finds applications in food additives and cosmetics due to its harmless nature. One of its notable uses is as an excellent solid lubricant in injection and extrusion processes. The pharmaceutical and cosmetic industries utilize calcium stearate as an anti-caking additive for powders and granules, as well as an additive for compressing tablets. In the construction industry, it serves as a hydrophobic agent, preventing moisture absorption and safeguarding building materials and structures. Calcium stearate is commonly employed as a key raw material, often in combination with other stearate salts like zinc stearate or barium stearate, to stabilize PVC (polyvinyl chloride). Within the rubber industry, it acts as a lubricant, release agent, and softener. In papermaking, calcium stearate enhances the printing capability and flexibility of paper and cardboard while preventing cracking and brittleness, thereby extending their lifespan.
