Description
Lupolen UHM 5000 is an ultra high molecular weight polyethylene (UHMW PE) with an average molecular weight of 5 million. The long molecular chains leed to unique properties:
Highest abrasion resistance of any thermoplastic materials, excellent impact strength, low friction, good chemical resistance and stress crack resistance.
Lupolen UHM 5000 is used in compression molding and ram extrusion processes. The material is supplied in form of coarse natural powder. The larger particle size and the very low fines content result in good free flowing property and less dust generation during handling and processing.
