Oxidized polyethylene wax primarily functions as a dispersant in masterbatch production. By enhancing the uniform distribution of pigment particles within the carrier resin, it improves the gloss, processability, and dispersion stability of the final product. ‌ ‌Enhancing Dispersion Uniformity： Oxidized polyethylene wax reduces van der Waals forces and electrostatic attraction between pigment particles, disrupting agglomerate structures to facilitate dispersion in the molten state. For instance, inorganic pigments like carbon black, which tend to aggregate due to high surface energy, achieve nano-level uniform distribution when oxidized polyethylene wax is added. ‌ ‌Improved Processing Performance：‌ Wax dispersants enhance melt flowability, reduce viscosity, decrease extruder energy consumption, and boost production efficiency. Simultaneously, their lubricating effect prevents heat buildup from friction between pigment particles during processing, avoiding equipment overheating or malfunctions. ‌ ‌Improved Product Performance：‌ Uniformly dispersed pigment particles reduce surface defects like color spots and streaks while enhancing gloss and mechanical properties. For applications demanding high dispersion quality—such as automotive components and appliance housings—polyethylene oxide wax prevents stress concentration issues caused by agglomeration.

This is particularly crucial for transparent products and those demanding high surface finish (e.g., sheets, films, foils). Low Volatility: Exhibits minimal volatilisation during high-temperature processing, minimising smoke and odour generation.

During the final stage of leather manufacturing—the finishing process— micro-wax is added to topcoat finishing agents (such as glazes and fixatives). Its primary purpose is to impart a premium feel and practical physical properties to the leather surface. Primary Functions: Hand Feel Improvement (Most Critical Function) Silky Smoothness: Micro-wax particles form an ultra-thin, smooth wax film on the leather surface, significantly reducing friction coefficients to create an exceptionally smooth and refined tactile sensation. Waxy Feel: Delivers a premium, waxed-like fullness and nourished hand feel. Flaw Concealment: Micro-wax particles can slightly fill minor scratches or imperfections on the leather surface, making the grain appear more uniform and flawless. Enhanced Physical Properties Scratch Resistance & Abrasion Resistance: Wax particles form a protective layer on the surface that effectively disperses and cushions external scratching forces, preventing permanent marks on the leather surface and improving durability. Anti-Sticking: Prevents treated leather pieces from sticking together due to temperature and pressure when stacked or rolled. Dulling Effect: Wax particles cause diffuse light reflection, reducing the coating's gloss level. By selecting different types and quantities of micro- wax, the leather's sheen can be precisely controlled from semi-matte to fully matte.

During PVC processing (such as extrusion, calendering, and injection molding), the molten PVC material becomes highly viscous due to heat and mechanical shear forces, readily adhering to the metal surfaces of processing equipment (such as screws, barrels, and molds). This leads to increased energy consumption, reduced production efficiency, rough product surfaces, and even decomposition. As an external lubricant, Fischer-Tropsch wax functions through the following mechanisms: Migration and spreading: During PVC plasticization, Fischer-Tropsch wax migrates from the PVC mixture interior to the melt surface. Formation of a barrier layer: A thin, uniform lubricating film forms between the melt surface and the metal surfaces of processing equipment. Reduced Adhesion and Friction: This lubricating film effectively lowers friction and adhesion between the PVC melt and metal equipment, achieving lubrication. Fischer-Tropsch wax is widely used in various rigid and flexible PVC products: Rigid PVC: This is the primary application area for Fischer-Tropsch wax. Window and Door Profiles: Provides excellent surface finish, facilitates extrusion, and reduces energy consumption. Pipes and fittings: Ensures stable extrusion and smooth inner/outer walls. Sheets and films: Such as transparent PVC sheets and advertising boards, maintaining lubrication without compromising transparency. Injection-molded products: Excellent demolding performance. Flexible PVC: Used as a lubricant and surface modifier in wire and cable compounds, artificial leather, flooring, etc.

Micronized wax is a solid powder with an extremely fine particle size (typically 1-20 microns). When added to an epoxy resin system and cured, its mechanism of action is as follows: 1. Floating Migration Effect: This is the primary mechanism. Due to poor compatibility between wax and epoxy resin, coupled with its low density, wax particles gradually migrate to the coating surface during curing. Formation of a protective layer: Ultimately, these wax particles create an extremely fine, uniform, and uneven wax film on the outermost layer of the coating. This film acts as a “sacrificial layer.” Reduced Friction Coefficient: When an object scrapes the coating surface, the force first impacts these protruding wax particles rather than directly affecting the epoxy resin matrix. This significantly lowers the surface friction coefficient, achieving scratch resistance and wear resistance. Generated Micro-Irregularities: The surface wax particles make complete optical contact difficult, thereby also contributing to a certain degree of matting effect (reducing gloss).

Microcrystalline wax has the following primary applications in candle making: Improving Texture and Performance Microcrystalline wax enhances candle hardness and surface smoothness while improving flexibility and extensibility, preventing cracking or deformation. For instance, adding hard microcrystalline wax increases paraffin's hardness and gloss, while soft microcrystalline wax is suitable for soft waxes like beeswax, improving demolding and reducing bubbles. ‌ Enhancing Adhesion and Stability Microcrystalline wax blends well with various waxes (e.g., soy wax, paraffin). By adjusting the melting point (e.g., using food-grade microcrystalline wax with a melting point below 60°C), it improves the adhesion of essential oils or decorative materials while reducing white streaks and cup separation issues. ‌ Extended Burn Time Candles containing microcrystalline wax burn more stably, resist dripping or black soot, and exhibit higher combustion efficiency.

Detailed Explanation of Fischer-Tropsch Wax Application in PVC: 1. Primary Function: Serves as an external lubricant During PVC processing (such as extrusion, calendering, injection moulding), the polymer melt undergoes friction and adhesion with the metal surfaces of processing equipment (e.g., screws, barrels, moulds) at elevated temperatures. The lubricant's role is to reduce this friction and adhesion. Function of Fischer-Tropsch wax: As a typical external lubricant, Fischer- Tropsch wax exhibits low compatibility with PVC. During processing, it migrates from the PVC melt to its surface, forming a thin lubricating molecular layer between the melt and metal equipment. Benefits: Reduced processing energy consumption: Minimises friction, lowering equipment drive power requirements. Prevents melt fracture: Reduces shear stress, preventing material degradation from excessive shear. Facilitates demoulding: Effectively prevents products from adhering to moulds during injection moulding or calendering. Enhances production line speed: Superior lubricity permits higher processing speeds.

Specific Advantages in Hot-Melt Adhesive Applications Adjustability: Fischer-Tropsch wax effectively modulates the initial gelation temperature and curing time of hot-melt adhesives, enhancing their plasticity and tensile properties. Low Viscosity and High Melting Point Advantages: Low-viscosity, high-melting-point Fischer-Tropsch wax also reduces the viscosity of polymers and resins, facilitating efficient resin blending and smooth hot melt adhesive pumping while maintaining appropriate surface wetting of polymers and resins. Food Contact Safety: Refined Fischer-Tropsch wax is contamination-free and odorless, making it suitable for hot melt adhesive applications requiring compliance with food contact standards. Its elevated melting point confers superior heat resistance to the adhesive. Low penetration enhances the adhesive's strength. The narrow carbon distribution range shortens open time and reduces curing time. The wax's stability ensures no migration or leaching, further optimizing hot melt adhesive performance.
