GUR 4152 | (PE-UHMW) | Celanese
材料文字说明
GUR 4152 UHMW-PE is a linear polyolefin resin in powder form with a
molecular weight of approximately 7.7 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.
