摘要: A structure for and method of producing large diameter seal rings. Preferred embodiments of the present invention make use of a co-extruded “support” layer of a polymer showing better weld quality and strength. The use of a co-extruded support polymer bonded to the functional polymer can be used to improve the strength of the entire weld, including the weld of functional polymer layer.
