Stearic acid is widely used in cosmetics, plastic plasticizers, release agents, stabilizers, surfactants, rubber vulcanization accelerators, water repellents, polish agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and other organic chemicals. Stearic acid can also be used as solvent of oil soluble pigment, crayon smoothing agent, waxed paper polishing agent, emulsifier of stearic acid glycerin, etc. Stearic acid is also widely used in the manufacture of PVC plastic pipes, plates, profiles and films, and is a heat stabilizer of PVC, with good lubricity and good light and heat stabilization. Applied in PVC pipes, stearic acid helps to prevent "coking" during processing and is an effective heat stabilizer in PVC film processing, while preventing discoloration of the finished film caused by exposure to sunlight. Stearic acid has become a functional additive for lubrication, plasticizing and stabilization of modified masterbatch. Stearic acid can effectively improve the coating activation effect of inorganic powder and increase the fluidity of the material. When the material with an absolute proportion of inorganic powder requires a large melt flow rate, appropriately increasing the content of stearic acid can significantly 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. Adding too much will cause the quality performance of plastic products to decline, and will also make mechanical devices such as the mold lip position of plastic products production equipment appear sticky, affecting production efficiency and product quality. Stearic acid mono or polyol esters can be used as cosmetics, non-ionic surfactants, plasticizers, etc. Its alkali metal salt is soluble in water, is one of the main components of soap, other metal salts can be used as waterproofing agents, lubricants, fungicides, paint additives and polyvinyl chloride stabilizer.
Application:
1 Widely used as plastic cold-resistant plasticizer, stabilizer, surfactant, release agent, rubber vulcanization accelerator, etc.
2 Used as a vulcanizing active agent for natural rubber, synthetic rubber (except butyl rubber) and latex, and also used as a raw material for plastic plasticizers and stabilizers. In medicine, it is used to prepare ointments, suppositories, etc., and is also used to manufacture cosmetics, candles, waterproofing agents, polishes and so on. The product is used in the food industry as a lubricant, defoamer and food additives stearate glycerin, stearate sorbitan anhydride ester, sucrose ester and other raw materials.
3 Can be used as a gas phase analysis standard, but also for the preparation of soap, cosmetics, pharmaceuticals and other organic chemicals.
4 Stearic acid can be used to determine the hardness of water. Determination of calcium, magnesium and lithium in turbidimetry. Solvent for determination of relative molecular weight. An active agent that promotes acidification. Commercial stearic acid is actually a mixture of 45% stearic acid and 55% palmitic acid, and contains a small amount of oleic acid, slightly fatty odor.
