This invention relates to a polymeric pipe, and more particularly a polymeric pipe where the pipe comprises a crosslinked polyolefin formed from extruded polyolefin comprising a photoinitiator and a reactive extrusion species. More particularly, this invention relates to the manufacturing of plastic pipes and tubing by utilizing co-rotating twin screw extrusion combined with photo-induced crosslinking, of thermoplastic polymers such as polyethylene, to produce PEX pipes and tubing.
本发明涉及一种聚合管材,尤其是一种聚合管材,其中管材包括由挤出聚烯烃形成的交联聚烯烃,挤出聚烯烃包括光引发剂和反应性挤出物质。更具体地说,本发明涉及利用同向旋转双螺杆挤压结合热塑性聚合物(如聚乙烯)的光诱导交联来制造 PEX 管材和管件。
