Package: Plastic bag, lined with PE bag, *0KG weight. Zinc stearate English name: Zinc Stearate Molecular formula: Zn(OOCH*5C*7)2 Property: It is white flammable nontoxic powder with specific gravity of 1.**5. It can dissolve in hot common solvent and acid, but not in water, ethanol or aether. It will become to glue when cooled after being heated in the organic solvent and be decomposed to stearate or salt when meet strong acid and can absorb moisture in air.

Package: Plastic bag, lined with PE bag, *0KG weight. Barium Stearate English name : Barium Stearate Molecular formula : Ba(OOCH*5C*7)2 Property: It is white toxic and flammable powder with specific gravity of 1.**5. it can not dissolve in water or 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. Specification : Testing items Excellent Grade 1 Free acid(accounted as stearic acid),%&#***4; 0.5 0.8 Melting point,&#***1;&#***5; **0 **5 Barium content, % *0.0 ±0.4 *0.0 ±0.7 Heating loss,% &#***4; 0.5 0.5 Fineness (mesh of 0.**5mm) %&#***5; *9.5 *9.5 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 larger quantity, however, you can see many patterns. Package: Plastic bag, lined with PE bag, *0KG in weight.
