Micronized polyethylene wax, also known as ultrafine or finely ground polyethylene wax, is a specialized form of polyethylene wax that has undergone a milling or micronization process to reduce its particle size to the micron (μm) range.
Micronized polyethylene wax is not necessarily melted but rather dispersed or incorporated into various matrices to achieve specific performance properties.
This finer particle size makes it suitable for various applications where improved dispersion, surface properties, or performance characteristics are desired. Here are some common applications of micronized polyethylene wax.
Coatings and Paints
In water-based and solvent-based coatings and paints, micronized polyethylene wax is added as a matting agent, anti-blocking agent, or slip additive. It is dispersed into the liquid paint formulation without melting to improve surface properties, such as texture, gloss, and scratch resistance.
Printing Inks
Micronized polyethylene wax is incorporated into printing ink formulations to enhance rub resistance, printability, and gloss without melting. It is typically dispersed into the ink during the ink manufacturing process.
Plastics and Masterbatches
In plastic processing and masterbatch formulations, micronized polyethylene wax is added to improve processing properties, such as flow, mould release, and surface finish. It is blended into the polymer matrix without melting.
Adhesives
Micronized polyethylene wax is used as an additive in adhesives to improve tackiness, reduce adhesion to non-target surfaces, and enhance release properties. It is mixed into the adhesive formulation without melting.
Rubber Compounding
In rubber compounding, micronized polyethylene wax can be added to reduce friction, improve processing, and provide a non-stick surface for rubber products. It is typically dispersed into the rubber compound without melting.
Textile and Fiber Processing
In textile finishing, micronized polyethylene wax is used to enhance the softness and feel of fabrics. It is applied as a dispersion or emulsion during the finishing process.
Cosmetics and Personal Care Products
Micronized polyethylene wax can be found in cosmetic and personal care products like creams, lotions, and lipsticks to improve their texture and spreadability. It is typically incorporated into these formulations without melting.
Paper and Packaging
In paper and packaging applications, micronized polyethylene wax is used to provide a barrier coating, improve printability, and reduce the coefficient of friction for easy handling and stacking. It is applied as a dispersion or coating.
Ceramics
In ceramics manufacturing, micronized polyethylene wax can be used as a lubricant and release agent for shaping and demoulding ceramic products. It is typically applied as a dispersion or emulsion.
