Oxidized polyethylene wax serves as a key multifunctional additive in PVC film processing, primarily employed to optimise processing performance and enhance product quality. Principal Functions and Effects Lubrication and Processing Performance Enhancement: OPE wax balances internal and external lubrication, reducing friction between PVC melt and equipment, minimising plasticisation delays, and increasing extrusion speed and production efficiency. Its polar groups also enhance compatibility with PVC molecular chains, preventing processing issues caused by excessive external lubrication. ‌Improved Dispersibility and Stability‌: In highly filled formulations, OPE wax adsorbs fillers and pigments, preventing agglomeration and enhancing dispersion efficiency to ensure uniform product performance.‌ Simultaneously, it synergises with thermal stabilisers by absorbing decomposed HCl, extending the processing window and reducing PVC thermal degradation.‌

Micronized wax primarily functions as a lubricant and processing aid in PVC extrusion, significantly enhancing processing performance and product quality. Mechanism and advantages of micronized wax in PVC extrusion: Micronized wax functions as both an external and internal lubricant during PVC extrusion, reducing intermolecular friction and enhancing melt flow. This increases extrusion rates while minimising equipment wear. Its spherical structure facilitates the formation of a uniform lubricating film, thereby reducing surface defects in the finished product and improving surface finish.

Micronized wax enhances ink performance through the following mechanisms: Improves surface properties: Reduces the coefficient of friction on printed surfaces, enhancing scratch resistance and anti-adhesion properties. Particularly suitable for flexographic, gravure, and offset printing processes. Optimises dispersibility and compatibility: Regular spherical particles disperse readily within ink systems without heating and exhibit excellent compatibility with pigments. PTFE-modified variants further enhance abrasion resistance. ‌Adjust gloss levels: Certain products (e.g., matting micronized wax powders) achieve a matte finish while maintaining coating uniformity.

Micronized wax is a functional additive widely employed in industrial paints to enhance the surface properties of the paint film, characterised by its fine particle size and uniform distribution. Primary Functions and Advantages ‌Enhanced Surface Properties‌: Micronized wax fortifies industrial paints against scratching, adhesion, and abrasion while imparting a smooth tactile feel. For instance, in coatings for steel structures or machinery, this reduces damage from routine friction.‌ ‌Improved Application Process‌: Incorporating micronized wax into formulations optimises rheological properties, yielding more uniform coatings and minimising air bubbles or orange peel effects. Certain micronized wax also offer matting effects, making them suitable for matt or semi-gloss industrial paints.‌ ‌Broad Adaptability: Micronized wax are compatible with solvent-based, water- based, and powder coating systems, demonstrating particular efficacy in industrial paints, can coatings, and wood finishes. Their spherical particle structure facilitates easy dispersion, allowing direct incorporation without complex pre-treatment.‌

Microcrystalline wax offers core advantages as a mould lubricant: Firstly, its excellent heat resistance and lubricity enable it to form a stable film during high-temperature injection moulding or die casting, reducing friction between the mould and moulded material, preventing sticking, and enhancing demoulding efficiency. Secondly, its good adhesion and film-forming properties ensure uniform coverage of the mould surface, providing sustained lubrication even within complex geometries and reducing mould wear. Furthermore, its high gel strength and crack resistance help maintain structural integrity during repeated thermal cycles, extending mould service life. In practical applications, microcrystalline wax is commonly employed as a pure product or in compound form: For instance, in rubber or plastic moulds, it may serve directly as a release agent or be blended with paraffin wax to enhance the latter's flexibility; in metal die casting, its lubricating properties reduce surface defects and improve product finish.

The primary functions of microcrystalline wax in sealants: Anti-adhesion and stain resistance: Surface protection: Forms an extremely thin, transparent wax film on the surface of cured sealants (such as silicone or polyurethane sealants). Contamination Prevention: This wax film effectively prevents contaminants such as construction site dust, cement slurry, and paint splatter from adhering to the uncured sealant surface, maintaining the joint's aesthetic appearance and cleanliness. Ease of Cleaning: Even if contaminants do adhere, they are significantly easier to wipe away. Controlling the Curing Process: For certain moisture-curing sealants (such as single-component silicone sealants and polyurethane sealants), the microcrystalline wax film on the surface can moderately slow the rate at which the top layer comes into contact with atmospheric moisture. Prevents ‘skin formation’: Avoids premature surface hardening that leaves the interior liquid, ensuring uniform and complete curing from the inside out. This delivers superior overall performance.

The moisture and oil repellency of microcrystalline wax primarily stems from its chemical inertness and physical barrier properties. It forms a continuous, dense coating that effectively blocks the penetration of moisture and oils. Its low permeability and high adhesion ensure the coating remains intact and resistant to flaking or peeling, thereby providing enduring protection across diverse substrates. In the packaging sector, microcrystalline wax is extensively employed for wax coating paper and cardboard. For instance, coating packaging paper with microcrystalline wax significantly enhances moisture resistance and oil repellency. This makes it suitable for applications such as frozen food cardstock and corrugated boxboard, preventing contents from becoming damp or oil-permeated. In food packaging, it is also employed in milk cartons, meat coatings, and bread wrapping paper, serving to isolate against moisture and oil penetration.
