Description
Aluminum stearate is an aluminum salt of stearic acid, which is a saturated fatty acid. It is used in various industries as a lubricant, release agent, and thickening agent. Some key points about aluminum stearate include:
- Lubricant: Aluminum stearate is used as a lubricant in the production of plastics, rubber, and other materials. It helps to reduce friction between the polymer chains and improve flow properties.
- Release Agent: Aluminum stearate is used as a release agent in the production of rubber and plastic parts. It helps to prevent the parts from sticking to molds and facilitates their removal.
- Thickening Agent: Aluminum stearate is used as a thickening agent in the production of paints, coatings, and cosmetics. It helps to improve the texture and viscosity of these products.
- Emulsifier: Aluminum stearate is used as an emulsifier in the production of emulsions and suspensions. It helps to stabilize the mixture and prevent separation of ingredients.
- Waterproofing Agent: Aluminum stearate is used as a waterproofing agent in various applications, including in the production of paper and textiles. It helps to improve the water resistance of these materials.
- Pharmaceuticals: Aluminum stearate is used in the pharmaceutical industry as an excipient in the production of tablets and capsules. It helps to improve the flow properties of powders and prevent them from sticking to the tablet press.
