Calcium Stearate
Name:Calcium Stearate
CAS NO.: 1592-23-0
Molecular formula:Ca[CH3(CH2)16COO]2
Apparence:Calcium stearate is fine withe fluffy powder,satiny hand feeling,soluble in hot- water,
toluene,alcohol,and other organic solvent, non-toxic,resolve into calcium and stearate acid when heat it to 400°c.
Mainly usage:
be widely used in food,medicine,cosmetic,plastic,rubber,etc. area.Used as lubricant,emulsifier,stabilizator,releasing agent,promoter,cosmetic basic material and so on.can improce the plastic products'
curdling speed,can be used to make thin film of food package and medcine appliance,meanwhile have effect as stabilizator;
improve heat resistance of plastic,improve weather fastness dyeing property and breathability.
