Celanese GUR® GHR 8110 PE-HD, Unfilled
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE)
Material Notes:	GHR 8110 is a linear polyolefin resin in powder form with a high molecular weight of ca. 600,000 g/mol calculated using Margolies' equation. This grade is melt processible and has good impact strength and abrasion resistance relative to many other resins, but not on the level of UHMW-PE. This resin is normally processed by compression molding. Information provided by Celanese
