Micronized oxidized polyethylene wax (MPOW) can be utilized in thermoplastic elastomers (TPEs) to achieve various desired properties and improve processing characteristics. Here are some common uses of MPOW in TPE formulations
Processing Aid
MPOW can act as a processing aid in TPE compounding and extrusion processes. It helps to reduce melt viscosity and improve flow properties, facilitating easier processing and enhancing production efficiency.
Surface Lubrication
Incorporating MPOW into TPE formulations can provide surface lubrication, reducing friction between the TPE material and processing equipment such as molds, dies, and extrusion screws. This helps to prevent sticking, improve mold release, and extend the service life of equipment.
Enhanced Moldability
MPOW can improve the moldability of TPE materials by promoting better flow into complex mold geometries and ensuring complete filling of mold cavities. This results in improved part quality and dimensional accuracy.
Reduced Surface Tackiness
TPEs often exhibit surface tackiness, which can be undesirable in certain applications. MPOW can help reduce surface tackiness by forming a thin, low-friction layer on the surface of the TPE material.
Improved Surface Finish
By reducing surface defects such as flow marks, weld lines, and surface roughness, MPOW can enhance the surface finish of TPE molded parts, resulting in a smoother and more aesthetically pleasing appearance.
Enhanced Weatherability
MPOW can improve the weatherability of TPE materials by providing a protective barrier against environmental factors such as UV radiation, moisture, and oxidation. This helps to extend the service life of TPE products exposed to outdoor conditions.
Impact Modification
In certain TPE formulations, MPOW can act as an impact modifier, enhancing the material’s toughness and resistance to mechanical impact. This is particularly beneficial in applications where durability and impact resistance are important.
Reduced Die Buildup
MPOW can help reduce die buildup and fouling during TPE processing, leading to fewer production interruptions, improved product quality, and reduced maintenance requirements for processing equipment.
