FEATURESFEATURES
- MIPELON™ is an ultra-high molecular weight polyethylene fine particle originally developed by Mitsui Chemicals. It features excellent distribution due to the spherical shape and narrow particle size distribution, and is able to improve the sliding properties, abrasion resistance, durability and quietness of a substrate when added to rubbers, coatings, greases and films. It can also be used as a filter by sintering the MIPELON™ itself.

<Academic Wave Abrasion Test Conditions>
Opposite Material: Glass
Speed: 60 reciprocating actions per minute
Load: 200 g
Stroke: 100 mm
MIPELON™ is added to a two-component urethane coating (polyester polyol-based) and spray coated on EPDM
> The low friction coefficient can be maintained, and the abrasion resistance is also higher than with PTFE

When MIPELON is added to a grease, durability is improved compared to the grease on its own.

<Measurement Conditions>
- LLDPE single-layer 40μm film
- Slip test between two pieces of film
- Test piece width: 63.5 mm
- Test speed: 100 mm / min.

Small spherical particlesExcellent dispersability
Compared with ordinary ultra-high molecular weight polyethylene, it boasts a smaller particle diameter and the world's smallest size. Additionally, the particles are spherical in shape, which offers superior dispersability.
Narrow particle size distributionSuitable for manufacturing high-quality products
It boasts a narrower particle size distribution than other particles such as PTFE, with less coarse particles.
Abrasion resistanceAdding MIPELON™ to various substrates improves their abrasion resistance.
Compared to PTFE, it boasts a lower coefficient of dynamic friction and is excellent as a sliding modifier.
Sliding propertiesAdding MIPELON™ to various substrates improves their sliding properties.
Compared to PTFE, it boasts a lower coefficient of dynamic friction and is excellent as a sliding modifier.
Chemical resistanceStable against acids, alkalis and organic chemicals
MIPELON™ has no functional groups nor side chains or double bonds, and possesses a highly crystallizable molecular structure. For this reason, it exhibits high stability against acids, alkalis and organic chemicals.
Non-water-absorbentDoes not easily absorb water or moisture
As it absorbs almost no water or moisture, no fluid swelling or hydrolysis occurs, and there is no need for pre-heating.
LightweightEnables reduced weight
With a density of 930 - 940 kg/m3, it is among the lightest engineering resins and is able to reduce the weight of products.
HygieneBrand that also complies with FDA regulations
Confirmation and registration has been obtained from the Japan Hygienic Olefin and Styrene Plastic Association, and preparations are underway for brands compliant with hygiene testing for synthetic resin containers and packaging, etc. (Ministry of Health, Labour and Welfare Notification 20. of 1982) and US FDA regulations (Code of Federal Regulation Title 21. Section 177.1520©2.2).
