Product Application

    • Used as a slip agent and opening agent for PP, CPP, BOPP, LDPE, LLDPE, EVA, PVC, PVDF, PVDC, PU films, and multilayer co-extruded films.

    • Effective for high-transparency agricultural films, ultra-high molecular weight polyethylene, and metallocene polyethylene.

    • Benefits: Significantly reduces dynamic and static friction, improves processability, and enhances packaging efficiency.

    • Provides smoothness, anti-sticking, and anti-soiling for printing inks.

    • Delays settling of pigments and fillers and facilitates redispersion.

    • Improves abrasion and scratch resistance, giving a smooth, high-quality surface finish.

    • Functions as a release agent, internal flow aid, and lubricant for chlorinated rubber, fluoro-rubber, EPDM, TPE-olefin, and PP/PE bottle caps.

    • Enhances processing, demolding, and surface finish in rubber and elastomer applications.

    • Acts as a release agent, surface smoothness and brightness enhancer for TPE, TEO, TPU, fluoro-rubber, and engineering plastics.

    • Serves as lubricant for LDPE calendered artificial leather, fiber materials, non-woven fabrics, and entertainment chips.

    • Used for high-wear plastics like PA (gears, shaft seals, bushings, slide plates) and as a lubricant/dispersant for ABS graphite fiber-modified materials.

    • Also effective as anti-adhesive in hot melt adhesives.
