UHMW-PE is a semi-crystalline polymer, it must be sintered by either compression
molding (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 be
fixtured during the cooling process to allow for shrinkage during annealing. Rough
machining should be done prior to stress-relieving so dimensional changes can
be accommodated during final machining.
