[Introduction]:
[Chemical formula]: Zn[CH3(CH2)16COO]2
[Characters]:
Zinc Stearate is white powder,greasy to touch without sand sense,fatty odor innoxiously, flammable, insouble in water, solve in hot ethanol, benzol etc. slowly decomposes into stearic acid and zinc salts when reacting with strong acid.
[Applications]:
Zinc stearate can be applied in the manufacturing of PVC innoxious products, and its performance will be better if use with calcium stearate and darium stearate, can improve the light stability of PVC products. Its dosage in the PVC usually not more than 1%. While applying in rubber products, PF,PE,PS and EPS polymer additives even the manufacturing of pencil core, dosage: usually 1%~3%.
