|---|
| GUR 4152 UHMW-PE is a linear polyolefin resin in powder form with a molecular weight of approximately 7.5 MM g/mol calculated using Margolies equation. The extremely high molecular weight of this resin yields several unique properties including superior abrasion resistance and impact strength. This and GUR 4150 resins have the best abrasion resistance 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 or ram extrusion.&& |
