Product Description
Description:
UTEC6541 is an Ultra High Molecular Weight Polyethylene with a molecular weight about 10 times higher than High Density Polyethylene (HDPE) resins. This extremely high molecular weight yields several unique properties to this polymer such as high abrasion resistance and impact strength and low coefficient of friction, what makes it a self-lubricating material.

Applications:
Applications which require highest wear resistance and the use of pigments and/or additives - technical parts RAM extruded and compression molded sheets, rods and profiles.
