Product Application
-
Films & Packaging
• 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.
-
Inks & Printing
• 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.
-
Rubber & Elastomers
• 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.
-
Engineering Plastics & Specialty 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.
