Product Description: The product is synthesized by the advanced process called melting method,which has high purity,good transparence and thermal stability.The quality indicators and use effect of the products all reach or surpass the similar improted or domestic manufactures by petrochemical professional detection, which is widely used in the fields of the plastic, rubber, papermaking and concrete as production and processing additives.

Product Name: Zinc stearate

Molecular formular: Zn(C17H35COO)2

Molecular weight: 631

Density: 1.095g/cm3

Physical and Chemical Properties:
White fine powder, combustible, greasy feeling, not dissolved in the water, ethanol and ether but dissolved in the hot organic solvents and acids.The colloidal material is formed along with the degression of the temperature after dissovled in the organic solvents and it is decomposed to stearic acid and Zinc stalts when it is reacted with strong acids.
