    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.
