As an internal and external lubricant: Reduce friction during extrusion and injection molding Smooth the mold surface, reduce mold sticking As a dispersant: Disperse pigments, glass fibers, fillers such as talc, CaCO₃ in plastic substrates (PP, PE, PA, ABS ...) Help the color to be even, without clumping Improve product surface: Increase gloss, smooth feeling Increase slip, reduce blocking phenomenon: Used for plastic films such as PE, PP, BOPP to prevent sticking Increase moisture resistance, anti-corrosion: In the paint, ink and rubber industries
Form Small granules, white powder Melting point ~140–150°C Density ~0.98 g/cm³ Thermal stability Good at plastic processing temperature (~200–300°C) Surface properties Has anti-stick, smooth ability Solubility in water Insoluble Good compatibility with many resins and fillers
