Products Description
Calcium Stearate is a high-purity and non-wet white powder manufactured with high quality stearic acid and calcium chloride. During manufacture, the particle size, shape, bulk and purity of calcium stearate are closely controlled to guarantee product uniformity.
Specification
-Excellent thermal stability
-Excellent Lubricity
-Good compatibility
-High corrosion resistance
Application
Calcium Stearate is used by rubber and plastic industries as an effective elastomer processing aid and release agent. The low chloride content allows for complete product dispersion in elastomers. Calcium Stearate reduces extruder pressure build-up of rigid PVC compounds when used as a processing aid during the manufacture of pipe, siding and injection molded fittings.
Package and Storage
Packing: 25kg/bag or 20kg/bag;
