Celanese GUR® 4120 PE-UHMW, Unfilled
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); UHMW PE (Ultra High Molecular Weight PE)
Material Notes:	GUR 4120 UHMW-PE is a linear polyolefin resin in powder form with a molecular weight of approximately 5.0 MM g.mol calculated using Margolies' equation. The extremely high molecular weight of this resin yields several unique properties including superior abrasion resistance and highest impact strength of all standard grades. Outstanding properties include a low coefficient of friction that results in self-lubricating, non-stick surfaces after processing. The resin is normally processed by compression molding, ram extrusion or free sintering of porous parts. Information provided by Celanese
