UHMW-PE is a semi-crystalline polymer, it must be sintered by either compression molding (UHMW-PE s UHMW-PE is a semi-crystalline polymer, it must be sintered by either compressionmolding (UHMW-PE sheet) or ram extrusion(UHMW-PE Rod, Pipe, Bar). UHMW-PE Powder, Annealing, prior to machining, helps remove the processing stresses caused by sintering. Finished machined parts can also be annealed, but such parts must befixtured during the cooling process to allow for shrinkage during annealing. Roughmachining should be done prior to stress-relieving so dimensional changes canbe accommodated during final machining.
