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. It 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.
