Properties

This product is mainly used as stabilizer and lubricant of PVC, and can be used as non-toxic soft film utensils such as food packaging and medical devices. As a halogen absorbent in polyethylene and polypropylene, it can eliminate the residual catalyst in the resin, which is a lubricant for resin color and molded products. It can also be used as a release agent for lubricants of thermosetting plastics such as phenolic and amino and polyester reinforced plastics, a thickening agent for lubricating grease, a waterproof agent for textile products and a smoothing agent for paint. Food grade calcium stearate is used as an anti caking agent to prevent powdery or crystalline food from aggregation and caking, so as to maintain its free flow.
