Barium stearate
1.Property: Barium stearate toxic,soluble in benzene,toluene and other non polarity of soluble,insoluble in water and ethanol,in water and ethanol,in the organic solvent cooling heating into jelly,in the air is absorbent,non sulfide pollution.when meeting strong decomposed into stearic acid and the barium salt.Barium stearate for PVC stabilizer and lubricant,in all alkaline earth metal stearate,Barium stearate long-team heat resistance is the best.
2.Application:Barium stearate in mainly used for soft transparent film,sheet,artificial leather,hard board,tube etc...also can be used as high temperature high temperature lubricant releasing agent and mechanical resistance.
3.Technical specification:
