Petrochemical Products

The primary functions of micro-wax in powder coatings: 1. Scratch and abrasion resistance Mechanism: During baking and curing, wax particles migrate to the coating surface, forming a thin, dense protective layer. This wax film possesses a low coefficient of friction and excellent lubricity, effectively reducing surface scratches and wear. Applications: Widely employed in sectors demanding high surface durability, such as household appliances (e.g., refrigerator and washing machine panels), aluminium extrusions, outdoor furniture, and automotive components. 2. Enhanced Flow and Hand Feel (Slipperiness Enhancement) Mechanism: Wax particles suspended on the surface render the coating smoother, not only reducing friction but also imparting a refined, silky- smooth tactile quality. Application: Products requiring specific tactile properties, such as electronic casings and office furniture. 3. Anti-adhesion (anti-caking) Mechanism: Micronised wax forms a micro-irregular ‘orange peel’ texture on the coating surface or provides physical separation. This reduces direct contact areas between coatings or between coatings and other surfaces, preventing adhesion during stacking or transportation. Applications: Critical for products requiring stacked storage, such as metal sheets and pipes.

Oxidised polyethylene wax may be employed in rust prevention applications. The polar functional groups on its molecular chain, such as carbonyl and hydroxyl groups, enhance adhesion to metal surfaces and protective performance in rust prevention applications. When incorporated into coatings or rust inhibitors, it forms a dense wax film upon cooling. This film exhibits excellent scratch resistance and effectively seals out moisture and oxygen, thereby achieving rust prevention.

Micronized wax particles form a microscopic ‘protective layer’ by floating on or protruding from the coating surface, thereby performing the following key functions: 1. Scratch resistance and abrasion resistance Mechanism: Wax particles are uniformly distributed within the coating, with some remaining exposed on the surface after curing. These hard particles withstand scratching forces from external objects, effectively shielding the underlying paint film. Application: Widely employed in sectors requiring frequent friction or contact, such as construction machinery, automotive OEM/touch-up paints, industrial flooring, and container coatings. 2. Enhanced Surface Smoothness and Tactile Feel Mechanism: Wax particles reduce the surface friction coefficient, minimising resistance when objects glide across the coating and imparting a smoother sensation. Simultaneously, they confer a refined, dry-to-the-touch finish. Applications: Products demanding superior surface tactility, such as electronic casings, domestic appliances (washing machines, refrigerators), and furniture wood finishes.

Micronized wax primarily functions as a processing aid and modifier in engineering plastics, with its core properties as follows: 1. Lubrication represents micro-wax's principal function, categorised into internal and external lubrication. Internal lubrication: Wax molecules disperse within the plastic melt, reducing friction between polymer chains and thereby lowering melt viscosity. External lubrication: Wax molecules migrate to the interface between the melt and processing equipment (such as moulds and screws), forming a lubricating film. Improved demoulding properties facilitate easier removal of products from moulds, reducing scrap rates. Enhanced surface finish yields smoother, more lustrous products. 2. Significant wear resistance and anti-slip properties When incorporated into engineering plastics, micronized wax forms a micro- lubricating layer on the product surface, lowering the surface friction coefficient. Application examples: Components requiring frequent motion and friction, such as gears, bearings, sliders, and guide rails, benefit significantly from micronized wax addition, which substantially extends their service life.

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.

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.

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.

Oxidized polyethylene wax finds significant application in the field of electronic component sealants due to its outstanding properties. Its unique molecular structure confers excellent polar compatibility, low volatility, and the absence of heavy metals, enabling it to meet regulatory requirements for food-grade and medical-grade plastic products. Specifically, oxidised polyethylene wax can be utilised in circuit board sealing and protection through specialised processes. For instance, by applying a coupling agent via brush coating, undergoing dehumidification treatment, and then dipping the circuit board into a mixture of molten oxidised polyethylene wax combined with tackifiers and liquid toughening agents, an effective waterproof and moisture-resistant wax film can be formed.
