Uses

Different sources of media describe the Uses of 6865-35-6 differently. You can refer to the following data:
1. Waterproofing agent; lubricant in metalworking, plastics, and rubber; wax compounding; preparation of greases; heat and light stabilizer in plastics.
2. 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.

Safety Profile

Moderately toxic by ingestion.When heated to decomposition it emits acrid smoke andfumes.
