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.
