The Role of Micro-Powder Wax in Leather Processing Improving Hand Feel: It significantly reduces the coefficient of friction on the leather surface, providing a smooth and soft feel, and is widely used in upholstery leather, garment leather, and shoe upper leather. Enhancing Surface Properties: It improves the abrasion and scratch resistance of the coating, prevents inter-layer adhesion, and enhances the leather’s water resistance, making it suitable for luggage and shoe leathers. Creating Special Visual Effects: When used on distressed-style leathers such as “Crazy Horse,” it can produce a polished, color-changing effect through buffing; the gloss level of the coating can also be adjusted as needed to achieve a matte or high-gloss finish.

Key Advantages of PPE in Photovoltaic Junction Boxes‌ ‌High-Temperature Resistance‌: The heat deflection temperature under load exceeds 190°C, with a melting point of approximately 268°C, ensuring structural stability in high-temperature environments. ‌Flame Retardancy: Possesses inherent halogen-free flame-retardant properties, meeting UL94 V-0 rating requirements, with a Glow Wire Ignition Temperature (GWIT) > 775°C and a Glow Wire Flammability Index (GWFI) > 960°C. UV Resistance and Weatherability: Effectively resists outdoor aging factors such as UV radiation, humid heat, and acid rain, ensuring a service life of over 25 years.

PPE is one of the five major general-purpose engineering plastics. Due to its excellent heat resistance, electrical insulation, low moisture absorption, and dimensional stability, it is widely used in the automotive and electronics industries. Applications in the Automotive Sector Lightweight components: Used to manufacture exterior body parts such as fenders, bumpers, wheel covers, and intake manifolds. Compared to metal, these components can reduce weight by up to 40%, contributing to carbon peaking goals. Engine Compartment Components: Components such as radiator grilles, high- voltage connectors, and battery pack assemblies can withstand high temperatures and coolant corrosion. Applications in the Electronics Sector High-Frequency, High-Speed Materials: Due to their extremely low dielectric constant and minimal susceptibility to temperature and humidity, these materials are widely used in 5G base station antenna radomes, high-frequency copper-clad laminates, radar radomes, and phase shifters.

In rubber processing, micro-powdered wax is primarily used as a processing aid and surface modifier. When added to rubber compounds, it significantly improves processing performance and ultimately enhances the service performance and surface quality of rubber products. Improved Processing Performance: As an effective internal and external lubricant, it significantly reduces frictional resistance during the mixing, calendering, and extrusion processes, thereby minimizing equipment wear and improving mixing uniformity and extrusion rates. Enhanced Product Abrasion Resistance: Wax microparticles disperse uniformly within the rubber, acting as “micro-bearings” that lower the surface friction coefficient of the finished product, significantly improving the abrasion and scratch resistance of rubber products.

Micropowder wax is an ultra-fine powder widely used in various industrial sectors, including coatings, inks, plastics, leather, and cosmetics, primarily due to its excellent abrasion resistance, scratch resistance, slip properties, matting effect, and anti-blocking properties. ‌Coatings and Inks‌ Enhances the abrasion resistance and scratch resistance of paint or ink films‌‌ Improves tactile feel, reduces the coefficient of dynamic friction, and provides a velvety smooth texture‌‌ Controls gloss levels and, when combined with matting agents, produces high- performance matte coatings/inks‌‌ Prevents pigment settling and enhances dispersion stability Plastics Processing Used as an external lubricant and release agent to improve flow and surface finish Used in color masterbatches, PVC pipes, injection-molded products, etc.

Micronized wax is used for demolding, primarily as an external release agent in the processing of polymer materials such as plastics, rubber, and coatings. By forming a lubricating film on the mold surface, it reduces the adhesion between the material and the mold, thereby ensuring smooth demolding, improving the surface finish of the finished product, and reducing the scrap rate. ‌Mechanism of Action of Micronized Wax in Demolding‌ Physical Barrier: Due to their fine particle size, micronized wax can be evenly distributed across the mold surface, forming a dense barrier layer. Reduced Interfacial Friction: Their lubricating properties reduce resistance to melt flow, improving demolding fluidity. Good Thermal Stability: Synthetic waxes, such as polyethylene wax and polypropylene wax, have high softening points and are resistant to decomposition or migration at high temperatures, making them suitable for engineering plastic processing.

As a high-performance, high-purity wax synthesized from coal or natural gas, Fischer-Tropsch wax plays an irreplaceable role in numerous industrial sectors due to its high melting point, low viscosity, high hardness, and completely non-toxic, odorless properties. Plastics and Polymer Processing This is the sector with the highest consumption of Fischer-Tropsch wax. It is primarily used as a highly effective lubricant to improve the flowability of plastic melts, facilitate easier demolding of products from molds, and enhance the surface gloss of the final products. PVC Processing: As an external lubricant used in the production of door and window profiles, pipes, and other products, it effectively prevents melt overheating and sticking, while imparting a high-gloss finish to the finished goods. Color Masterbatches: As a pigment dispersant, it helps distribute pigments evenly throughout the plastic, making it particularly suitable for manufacturing ultra-fine pigment masterbatches used to color synthetic fibers.

Microcrystalline wax can be used as a lubricant in metalworking, primarily due to the following properties: ‌Excellent lubricity and film-forming properties‌: Microcrystalline wax forms a uniform, dense protective film on metal surfaces, effectively reducing friction, minimizing tool wear, and improving machining accuracy and surface finish. ‌‌. ‌Rust and corrosion protection‌: During metalworking, microcrystalline wax also acts as a rust inhibitor, blocking moisture and corrosive agents to protect workpieces and equipment. ‌‌. ‌Thermal stability and compatibility‌: Microcrystalline wax typically has a melting point range of ‌60–90°C‌, remaining stable at most metalworking temperatures. It is also miscible with other lubricating components such as mineral oil and vegetable wax, facilitating the formulation of composite cutting fluids or greases‌‌.

Micronized wax is primarily used as a highly effective dispersant in colour masterbatches. Its role and mechanism of action in colour masterbatches are as follows: Core role: Highly effective dispersant Mechanism of action: With a particle size similar to that of the pigment, it effectively isolates and wets the pigment particles, preventing their re- agglomeration. Practical benefits: Improves pigment dispersion and tinting strength, reduces pigment consumption and costs, whilst minimising filter screen blockages. Core role: Processing aid Mechanism of action: Reduces the viscosity of the polymer melt, improving the flow properties of the compound during processing. Practical benefits: Enhances production efficiency, reduces energy consumption during processing, and ensures smoother production.

Fischer-Tropsch wax is a high-performance viscosity modifier, primarily used to regulate flow properties, fast-drying characteristics (i.e. shortening the open time) and heat resistance. Regulating flow and wetting properties: Fischer-Tropsch wax has extremely low viscosity at high temperatures, significantly improving the flow properties of the adhesive. This helps the hot-melt adhesive to penetrate and wet the surface of the substrate more effectively, thereby forming a stronger bond. Reducing curing time: With a high pour point and narrow carbon distribution, Fischer-Tropsch wax shortens the time taken for hot-melt adhesives to transition from a molten to a solid state, achieving ‘fast drying’. This is crucial on high-speed packaging production lines, as it prevents the adhesive from being ejected before it has dried.
