USES  as below,

PVC

Compounds, Rigid PVC Pipes and Cables, PVC Profiles and Flooring, PVC Footwear,

Master Batches. BARIUM STEARATE is heat stabilizer and lubricant for

transparent PVC Compound. It is generally used in conjunction with other

stabilizers Cadmium Stearate and Lead Stearate.

 A combination of Barium, Zinc and CALCIUM

STEARATE can be used as a stabilizer in food grade PVC processing. Due to high

melting point BARIUM STEARATE is used for high-speed calendaring. It is used as

a flatting and sanding agents in lacquers, coatings and inks.

It is also used as drying lubricants and dusting agents for rubbers.

Metallic

salts of fatty acids (called soap) are primarily used as cleansing agent

(mainly sodium- and potassium-) which their molecules attach readily to both

polar molecules (of water) and non-polar molecules (of grease or oil). The long

hydrocarbon chains are non-polar (and hydrophobic) repelled by water and the

salt end molecules are ionic (and hydrophilic) water soluble. Soaps differ

according to the type of fatty acid and length of the carbon chain and

according to the alkali employed. Fatty acids with longer chains are insoluble.

If sodium hydroxide is used as the alkali, hard soaps are formed; potassium

hydroxide yields soft soaps. Soap salts are used as insecticides, herbicides,

fungicides and algaecides. The lipophilic carbon chains infiltrate and destroy

the lipoprotein matrix of the insect's cell membranes. Food grade soap salts

are used also as  general purpose food

additives. Aluminum, calcium, magnesium, lead, zinc or other metals are used in

place of sodium or potassium for soaps to be used in industry. Metallic salts

of fatty acids are used as stabilizer and plasticizer in plastic industry as

well as in cosmetics. They are used as flatting and sanding agents in lacquers,

coatings & inks. They can be applied in tablet manufacturing. They are used

as drying lubricants and dusting agents for rubbers. They are used as catalysts

in chemical synthesis and emulsifiers for emulsion polymerization of synthetic

rubber and resin which can be approved for use in food contact applications.

They are used as waterproofing additives and ointments.

octadecanoate;Barium Stearate (Light);barium dioctadecanoate;octadecanoate,

barium salt (1:1); Molecular formula : Ba(OOCH35C17)2 Property: It is white

toxic and flammable powder with specific gravity of 1.145. it can not dissolve

in water or ethanol and will become to glue when cooled after being heated in

the organic solvent. It will be decomposed to stearate or salt when meet the

strong acid. Specification : Testing items Excellent Free acid(accounted as

stearic acid),%? 0.5 Melting point,?? 210 Barium content, % 20.0 ?0.4 Heating

Application : It has good stability and lubrication, better than calcium

stearate, but poorer than lead stearate. It is better if used together with

cadmium, zinc and epoxy compound. It is mainly used for transparent film and

flake, imitation leather, cable granule, rigid material, etc. when in a larger

Usage:

It has good stability and lubrication, better than calcium stearate, but poorer

than lead stearate. It is better if used together with cadmium, zinc and epoxy

compound. It is mainly used for transparent film and flake, imitation leather,

cable granule, rigid material, etc. When in a large quantity, however, you can

see many patterns.
