Product Description

Calcium Stearate is widely used in battery industry as oxidant and bleach. It is also used as polymerization initiator, fiber industry desizing agent; And can be used as metal and semiconductor material surface treatment agent, printing circuit etching agent; It is also widely used in oil fracturing, flour and starch processing industry, grease industry, and in photography industry to remove sea waves.

Calcium stearate is White powder, insoluble in water, cold ethanol and eth yl ether, soluble in organic solvents such as hot benzene, benzene and turpentine, slightly soluble in hot ethanol and eth yl ether.When heated to 400ºC, it will decompose slowly and be flammable. When met with strong acid, it will decompose into stearic acid and corresponding calcium salt, which has hygroscopic property.
