ABSTRACT:
A method of producing reformed crosslinked polymer articles provides reformed crosslinked articles free of visible and objectionable folds, seams, and interfaces on reformed surfaces thereof. In a preferred embodiment, a method includes the steps of extruding a silane-grafted polyethylene tube, heating an end of the tube, reforming the end of the tube to produce a radially enlarged sealing surface thereon, cooling the reformed tube, and curing the reformed tube to produce an increase in the degree of crosslinking of the polyethylene material.
