Zinc Stearate Powder CAS No.:557-05-01 As White Powder Used For Rubber
Introduction
1,Zinc Stearate (Zn-55) is a neutral zinc soap and most powerful
mould release agent. Zinc Stearate has hydrophobic effect and
insoluble in water, soluble in hot ethanol, benzene, toluene,
turpentine and other organic solvents.
2, Zinc stearate is White, hydrophobic powder with a slight,
characteristic odor. Mp: 130°C. Density: 1.1 g cm-3. Insoluble in
water, ethyl alcohol and diethyl ether. Soluble in acids.
Non-toxic. In technical grades, the percentage of zinc may vary
according to the intended use. Products with less than the
theoretical amount of zinc are more acidic.
Applications
Zinc stearate is an "activator" for rubber vulcanization by sulfur
and accelerators. As discovered in the early days of vulcanization,
zinc has a beneficial effect on the reaction of the sulfur with the
polyolefin. The stearate is a form of zinc that is highly soluble
in the nonpolar medium of the polyolefins.
Being lipophilic, Zinc stearate functions as a phase transfer
catalyst for the saponification of fats.
