Ope wax for leather processing
Oxidized polyethylene wax serves as a key component in finishing agents, performing the following functions: Providing excellent gloss Mechanism: During leather smoothing or embossing, wax particles within the wax emulsion melt under heat, forming an extremely thin, continuous transparent wax film on the leather surface. This film reflects light like a mirror, producing gloss effects ranging from natural to high sheen (depending on dosage and process). Effect: Enhances the leather's appearance, imparting a brighter, more luxurious look. Improves Handfeel Mechanism: The wax film inherently possesses smooth and moisturising properties. It reduces the friction coefficient on the leather surface, resulting in a smoother, finer, and silkier tactile sensation. Effect: Significantly enhances the leather's sensory quality, making it a crucial adjuvant in producing premium leather goods such as automotive upholstery, high-end furniture leather, and apparel leather.

OPE wax used for fibre lubricant
In the production of synthetic fibres (such as polyester, nylon, and polypropylene) and natural fibres, fibre lubricants (or ‘oils’) are indispensable additives. Oxidized polyethylene wax primarily serves the following functions: 1. Excellent lubricity Friction reduction and wear resistance: During high-speed spinning, stretching, texturing, and weaving processes, fibres undergo intense friction against metal guides and ceramic friction plates. Oxidized polyethylene wax forms a robust, smooth lubricating film on the fibre surface, effectively lowering the coefficient of friction. Effect: Prevents fibre pilling and breakage, reduces powder shedding, and enhances production efficiency and yield. 2. Outstanding Antistatic Properties Synthetic fibres readily accumulate static electricity during processing due to friction, leading to issues such as fibre entanglement, poor dispersion, and dust attraction. The polar functional groups of oxidized polyethylene wax exhibit hygroscopic properties, facilitating charge dissipation and thereby providing effective antistatic performance. Contact:

Ope wax used for PVC cable production
Oxidized polyethylene wax serves primarily as an excellent lubricant in PVC cable manufacturing, significantly enhancing processing properties while improving the smoothness and gloss of finished products. The carbonyl and hydroxyl groups on its molecular chain enhance compatibility with polar resins, effectively preventing material adhesion during extrusion and improving demoulding performance. Beyond its lubricating function, it also serves as a dispersant to facilitate the uniform distribution of pigments and fillers, proving particularly suitable for high-speed extrusion and other scenarios demanding superior processing efficiency. Oxidised polyethylene waxes of varying densities can be tailored for diverse PVC products; for instance, high-density grades are frequently employed in cable compounds. Contact:

micronized polyethylene wax for filler masterbatch production
Micronized polyethylene wax primarily functions as a dispersant and lubricant within masterbatch formulations, enhancing pigment dispersion, improving processing properties, and boosting product gloss. Enhanced dispersion performance: By wetting pigment surfaces and penetrating agglomerates, micronised polyethylene wax weakens interparticle cohesive forces. This facilitates easier fragmentation of pigments under shear stress, thereby improving dispersion uniformity. Processing performance optimisation: Its lubricating effect reduces masterbatch system viscosity, enhances material flowability, minimises equipment friction, and extends machinery lifespan. Simultaneously, its micronised form facilitates more uniform dispersion within the system, boosting production efficiency. Product quality improvement: Incorporation enhances compatibility between masterbatch and base resin, yielding smoother, finer plastic surfaces with markedly improved gloss. Contact:
