Barium Stearate
1.Molecular formula: Ba(C17H35COO)2
2.Property:
It is white toxic and flammable powder with specific gravity 1.145. It's insoluble in water and 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.
3.specifications:

Heating loss,% ≤ | 0.5 | 0.5 |
Fineness0.075 mesh, % ≥ | 99.5 | 99.5 |
4.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 large quantity, however, you can see many patterns.
