Micronized oxidized polyethylene wax (MOPEW) is a specialized form of polyethylene wax that has undergone a micronization process followed by oxidation. This treatment alters the physical and chemical properties of the polyethylene wax, making it suitable for various industrial applications. MOPEW particles are finely micronized, typically ranging in size from a few micrometers to tens of micrometers, and they contain polar functional groups such as carbonyl and hydroxyl groups on their surface due to oxidation.
Here are some common characteristics and uses of MOPEW:
Surface Protection
MOPEW can provide surface protection in coatings, paints, and inks, improving scratch resistance, abrasion resistance, and durability. It forms a protective layer on the surface, enhancing its resistance to wear and environmental degradation.
Matting Agent
It can act as a matting agent in coatings and paints, reducing gloss and creating matte or satin finishes. The fine particles of MOPEW scatter light, resulting in a lower gloss level and a softer appearance.
Improved Dispersion
MOPEW enhances the dispersibility of pigments and other additives in formulations, leading to more uniform distribution and better performance. It helps prevent agglomeration and settling of particles, ensuring consistent results.
Processing Aid
In plastic and rubber processing, MOPEW acts as a lubricant and processing aid, improving flow properties, mold release, and extrusion characteristics. It facilitates easier processing and enhances the surface finish of molded or extruded products.
Adhesion Promoter
MOPEW improves adhesion in adhesives and sealants, enhancing bonding strength and performance. It promotes better adhesion to a variety of substrates, increasing the reliability of bonded assemblies.
Personal Care Products
MOPEW is used in personal care products such as cosmetics, lotions, and creams as an emollient and viscosity modifier. It provides a smooth, soft texture and helps stabilize formulations.
Textile Finishing
MOPEW provides water repellency, lubrication, and anti-blocking properties in textile finishing processes. It helps prevent fibers from sticking together and enhances the performance of treated fabrics.
Seed Coatings
In agriculture, MOPEW is used in seed coatings to improve flowability, adhesion, and moisture protection. It helps ensure uniform coverage of active ingredients and additives, enhancing seed performance and viability.
Overall, MOPEW offers a wide range of benefits in various industries, including improved processing, enhanced performance, and added functionality to end products. Its versatility and unique properties make it a valuable additive in many formulations and applications.
