Calcium stabilizer powder
1.Property: Calcium stearate solution in toluene,ethanol,benzene and other organic solvents,insoluble in water,heated to 400°C when slowly decomposition,flammable,case of acid decomposed into stearic acid and calcium salt,water inhibition,non-toxic,no curing pollution,long-term heat stability.
2.Application:Calcium stearate is PVC heat stabilizer and a variety of plastic processing lubricant,mold release agent,in the hard ware ,with basicity lead salts,soap can improve the curdling speed.also used in food packaging,medical equipment and other requirements of non-toxic soft film and equipment.can be made of polyethylene,polypropylene halogen absorber,to eliminate the adverse effects of residual catalyst on the stability of color and .in rubber processing as plasticizer,lubricating grease thickening agent,waterproofing agent of textile,paint flatting agent,manufacturing plastic record of plasticizer.
