Barium stearate CAS 6865-35-6

Barium stearate, also known as barium octadecanoate, chemical formula Ba(C18H35O2)2, molecular weight 704.13, white fine powder, insoluble in water, insoluble in cold ethanol, soluble in hot ethanol, benzene, toluene and other non-polar solvents. Melting point 160°C, relative density 1.15, insoluble in water, insoluble in cold ethanol, soluble in hot ethanol, benzene, toluene and other non-polar solvents, dissolved in organic solvents after heating and cooling into a gel. Decomposed into stearic acid and corresponding barium salt when met with strong acid. It has water absorption in air. It can be used as waterproof products, filler of alkali chirp, also can be used as high temperature resistant lubricant and filler of machine; light and heat resistant stabilizer of PVC and other plastics, high temperature resistant powder molding agent of rubber products and so on. Barium stearate is poisonous, with toxicity factor T=2. Typical symptoms of poisoning are vomiting, abdominal pain, dysentery, increase in blood pressure, and pulse beat disorder.

1. Performance and use:

Barium stearate is not generally used as a stabilizer, but is an important film-calendering lubricant. It is generally used in conjunction with other stabilizers such as Cadmium Stearate and Lead Stearate.

Barium stearate can be used as a flatting and sanding agents in lacquers, coatings and inks and as a drying lubricant for rubbers.

Barium stearate is used in dry - salt fire extinguishers to prevent caking.

Waterproofing agent; lubricant in metalworking, plastics, and rubber; wax compounding; preparation of greases; heat and light stabilizer in plastics.
