[Stearate supply and procurement] Stearate is very important in the grease industry

Grease: a thick, greasy semi-solid. Used for the friction parts of machinery to lubricate and seal. Also used on metal surfaces to fill gaps and prevent rust. Mainly made of mineral oil (or synthetic lubricant) and thickener. The working principle of grease is that the thickener keeps the oil where it needs to be lubricated. When there is a load, the thickener releases the oil, thus providing lubrication.

Stearate is very important in the grease industry. The following suppliers of zinc stearate and calcium stearate are introduced to you. The application of stearate in the grease industry:

Stearate has the effect of gelling mineral oil and polar solvents. It is heated together with these liquids and cooled into a colloid. . The stearates used in the stearate mineral oil system of lubricating grease are mostly metal salts such as calcium stearate, aluminum stearate, lead stearate, lithium stearate, magnesium stearate, zinc stearate, etc. , the added amount is several percent to more than ten percent of mineral oil.

The stearate in grease mainly plays the role of gelling, increasing pour point and increasing consistency. Lubricating oil can be made by thickening it with calcium fatty acid. Grease containing aluminum soap can be obtained by reacting aluminum isopropoxide with stearic acid and toluic acid. When 1% fish oil fatty acid lead and sulfur modified oil are mixed with aluminum soap, barium soap, calcium soap mixture, lithium soap or sodium soap, the grease produced has extrusion resistance. Lithium stearate with hydroxyl group can also be used to make high-pressure resistant grease.
