Calcium Stereate

Calcium Stereate is the calcium salt of distilled, hydrogenated fatty acids. Products differ mainly in degree of over basing, apparent density and particle fineness of powders.

alcium stereate is used as a catalyst neutralizer and/or lubricant in polypropylenes. Precipitated versions provide finer particle sizes and are used in specialized polypropylene uses such as thin fibers and films. Calcium Stereate does not melt, but reaches a plastic phase at normal processing temperatures and sometimes does not disperse as well as might be expected.
