Stearicacid sound quality

The main purpose:
Stearic acid is widely used in cosmetics, plastic plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals Products and other organic chemicals. Stearic acid can also be used as a solvent for oil-soluble pigments, crayon slip agent, wax paper polish, emulsifier for glycerol stearate, etc. Stearic acid is also widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a heat stabilizer for PVC, with good lubricity and good light and heat stability. When used in PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective heat stabilizer in the processing of PVC films, and at the same time prevents the discoloration of the finished film caused by exposure. Stearic acid has become a lubricating, plasticizing, and stable functional additive for filled masterbatch. Stearic acid can effectively improve the activation effect of inorganic powder coating and increase the fluidity of the material. For materials with inorganic powder as an absolute part, when the melt flow rate is large, the content of stearic acid can be increased appropriately. Increase the melt flow rate of the material. However, the amount of stearic acid in the filled modified masterbatch also has a limit value, which is generally controlled at about 1% of the total mass. If the added amount is too large, the quality and performance of the plastic products will be reduced, and the mechanical lip position of the plastic product production equipment and other mechanical devices will appear sticky, which will affect the production efficiency and product quality. The monobasic or polyhydric alcohol esters of stearic acid can be used as cosmetics, nonionic surfactants, plasticizers, etc. Its alkali metal salt is soluble in water and is one of the main ingredients of soap. Other metal salts can be used as waterproofing agents, lubricants, bactericides, paint additives and polyvinyl chloride stabilizers.
