Mitsubishi Chemical Advanced Materials Chirulen® 1020 HXLPE MediTECH Compression Molded and Irradiated UHMWPE Form
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE); UHMW PE (Ultra High Molecular Weight PE)
Material Notes:	MediTECH Compression Molded and Irradiated UHMWPE Form, produced from Celanese GUR 1020 resin. Chirulen® 1020, 75 kGy, Above Melt Annealed materials maintain the toughness of UHMWPE, while providing the enhanced wear properties of the more highly crosslinked polymer, with the stability provided by the above melt annealing for free radical neutralization. ISO Cell Designation: Thermoplastic ISO 11542-PE-UHMW QD, 2-2-2, ASTM Cell Designation: S-UHMW-PE0111A111 Material evaluated based on ISO 5834-1 Type 1, ISO 5834-2 Type 1, and ASTM F648 Type 1.
