description Product Description
Widely used as a lubricant in the plastics and rubber industries, it helps improve processing by reducing friction during molding and extrusion. It acts as a release agent, preventing materials from sticking to molds or processing equipment. Commonly added to thermoplastics like PVC and polyolefins to enhance flow and dispersion of fillers. Also used in powder coatings and paints to provide a smooth, matte finish and improve anti-blocking properties. In cosmetics and pharmaceuticals, it serves as a thickening agent and water repellent in powders and ointments. Frequently incorporated into greases and waxes to modify texture and consistency. Its hydrophobic nature makes it useful for moisture resistance in various industrial formulations.
