Lithium stearate is a chemical compound with the formula LiO2C(CH2)16CH3. It is formally classified as a soap (a salt of a fatty acid). Lithium stearate is a white soft solid, prepared by the reaction of stearic acid.
Lithium stearate and lithium 12-hydroxystearate are lithium soaps, and are components of lithium grease.
Lithium stearate is a white powdered compound, chemical formula LiC18H35O2, CAS accession number 4485-12-5. Stabilizing agent; Lubricant; Petroleum industry corrosion inhibitors; Alkaline zinc-manganese battery cathode material additives
Lithium Stearate can be used as PVC heat stabilizers in transparent products, when use in conjunction with phthalate plasticizers, the film transparency of products is good and does not appear white mist. Lithium Sterate is easier to melt in ketones compare with other stearates, thus little influence on the embossing operation. It is non-toxic substitute for barium soap and lead soap. The product can also be used in conjunction with the phospholipid acid plasticizers. This product can also be used as an external lubricant for nylon, phenolic resin, rigid polyvinyl chloride (maximum amount of 0.6 % ) In addition, the goods can be used as construction waterproof, impermeable and so on.
1.Widely used as a heat stabilizer in PVC rigid products, with salt-based lead salts and lead soap, it can improve the gelation speed.
2.As a halogen absorber in polypropylene and polyethylene, it can eliminate the negative effects of residual catalysts in the resin on the colour and stability of the resin.
3.Also used as a lubricant for polyolefin fibres and mouldings.
4.Used as a mould release agent, plasticizer, thickening agent for grease, waterproofing agent for textiles, smoothing agent for paint industry, etc. in rubber processing.
5.It can also be used as food additive, feed additive, cosmetics, etc
