wallpapers News 2020-12-10
Stearic acid, or octadecanoic acid, has a molecular formula of C18H36O2, which is produced by the hydrolysis of fats and oils, and is mainly used to produce stearates. Each gram is dissolved in 21ml ethanol, 5ml benzene, 2ml chloroform or 6ml carbon tetrachloride.
Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, crayon slip agents, wax paper polishes, and emulsifiers for glyceryl stearate.

The product is used as a lubricant, defoamer and food additives in the food industry as raw materials for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as raw material for additives and raw materials for daily chemical products.
Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stability.
In plastic PVC pipes, stearic acid helps prevent "scorching" during processing. Adding in PVC film processing is an effective heat stabilizer, and it can also protect the finished film from exposure to sulfide. Discoloration.
