Description of Lithium Stearate

Lithium stearate, also known as lithium octadecanoic, is stable at room temperature and pressure. It is insoluble in water, ethanol, and ethyl acetate. A colloid is formed in mineral oil.

Lithium stearate is mainly used as a heat stabilizer for polyvinyl chloride. It is suitable for transparent products. When used in combination with phthalate plasticizers, the product does not show white fog, and the transparency of the film is good. This product is better than other hard fats. The acid salt is quickly melted in the ketone, so it has little effect on the embossing operation. This product can be used as a non-toxic substitute for saponin and first soap. This product can also be used as an external lubricant for nylon, phenolic resin, and hard — Polyvinyl chloride. The maximum dosage is 0.6 parts.


Parameters of Lithium Stearate

Molecular formula: C17H35COOLI

Molecular weight: 289.94

Physical properties: white fine powder.

Indicator:

Lithium oxide content /% 5.0-5.6

Heating loss /% ≤1.0

Free acid (calculated as stearic acid)% ≤0.5

Fineness (0.075mm sieve) /% 99%


Advantages of lithium stearate:

1 It has good stability and can reduce the overall cost of the enterprise. It is mainly used for PVC heat stabilizers suitable for transparent products. It has good performance, which can reduce the general cost of the enterprise.

2 It has good transparency, good dispersion, reducing product defect rate. It is used in combination with a phthalic acid plasticizer. The product it does not have white fog but has good transparency. It is more soluble in ketones than other stearates and has less influence on embossing operation.

3 It is used as a non-toxic substitute for barium soap and lead soap, or as an external lubricant. Wide range of applications. Its maximum amount is 0.6.


Lithium tristearate uses:

1. Widely used in high-temperature lubricants;

2. Plastic industry stabilizers;

3. Emulsifying and dispersing agent for grease, gel, crayon, and cosmetics;

4. Powder metallurgy lubricants;

5. Corrosion inhibitors in the petroleum industry.


Packaging and preservation of Lithium tristearate 

The packaging of this product is 20~ 50kg/drum lined plastic bag double layer packaging, pay attention to dry storage.
