Product Introduction:

Stearic acid Powder, CAS: 57-11-4, is a white or light yellowish white solid. It is one of the main long-chain fatty acids that make up oils. It exists in animal fats, oils and some vegetable oils in the form of glycerides. In alcohol and acetone, it is easily soluble in ether, chloroform, benzene, carbon tetrachloride, carbon disulfide, amyl acetate and toluene, etc. It has a melting point of 69.6°C and is one of the main components of grease.

Almost all fats and oils contain stearic acid with varying content, and the content in animal fat is relatively high. For example, the content in tallow can reach 24%, and the content in vegetable oil is less, tea oil is 0.8%, and palm oil is 6%. , But the content of cocoa butter is as high as 34%.

The main purpose:

Stearic acid Powder is mainly used to produce sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, and potassium stearate. Widely used in the manufacture of cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishes, metal soaps, metal mineral suspending agents, softeners, pharmaceuticals and other organic chemicals.

It can also be used as a solvent for oil-soluble pigments, as a slip agent for crayons, as a wax paper polish, and as an emulsifier for glyceryl stearate. This product is a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters, used as lubricants, defoamers and food additives in the food industry. It is used as a raw material for additives and as a raw material for household chemical products. Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films.

Stearic acid is a heat stabilizer for PVC and has excellent lubricity and light and heat stability. In plastic PVC pipes, stearic acid helps prevent “soot” during processing. When added to PVC film processing, it is an effective heat stabilizer, while also preventing discoloration of the finished film from exposure to sulfides.

Application field:

  • Rubber industry
    Stearic acid Powder plays an important role in rubber synthesis and processing. Stearic acid Powder is a vulcanization activator widely used in natural rubber, synthetic rubber, and latex, and can also be used as a plasticizer and softener. In the process of producing synthetic rubber, stearic acid must be added as an emulsifier, and Stearic acid Powder can be used as a foaming agent in the production of foamed rubber, and stearic acid can be used as a release agent for rubber products.
    Stearic acid Powder is added as an auxiliary material, and although the proportion is small, it is essential. After adding in a certain proportion in the rubber (tire) processing process with vegetable oil fatty acids, to summarize, there are four aspects as follows:
    1. Softening and plasticizing effect;
    2. As an external lubricant;
    3. Favorable for overall diffusion of carbon black, white carbon black and zinc oxide.
    4. It can react with zinc oxide or alkali accelerator to promote its activity, it is also the main vulcanization accelerator and can also act as a second accelerator. It can accelerate curing.
  • Cosmetics industry
    Stearic acid is used as an emulsifying agent in two skin care products, Vanishing Cream and Cold Cream, resulting in a stable, white paste. Stearic acid Powder is also a key ingredient in making almond honey and milk. Stearic acid soap esters are more widely used in the cosmetic industry.

Supplement other related knowledge:

  • Industrial products
    • Industrial products are white or pale yellow particles or lumps, a mixture of 45% stearic acid and 55% palmitic acid, containing a small amount of oleic acid with a slight fatty odor. Industrial products are grade 1 (previously called three-press, after three-press), second-stage (previously called two-press, after two-press) and three-stage (formerly known as one-pressed, squeezed once or not squeezed).
    • It is a mixed acid composed mainly of Stearic acid Powder and palmitic acid. Primary and secondary Stearic acid Powder is a lustrous or crystalline, white waxy solid. Tertiary stearic acid is a pale yellow waxy solid.
