A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.
Typical applications include military uniform and gear components, automotive interior trim, athletic padding, environmentally friendly protective packaging, air filtration, abrasive nail files, and protective cases and inserts utilizing a variety of materials such as foam (cross-linked polyethylene, reticulated, melamine, specialty foam ...
Polyethylene Piping in Australia, made from HDPE material. Polyethylene has been successfully used for the safe conveyance of potable and waste water, hazardous waste, and compressed gases for many years. Two variants are HDPE pipe (high-density polyethylene) [8] and the more heat resistant PEX (cross-linked polyethylene, also XLPE).

Polyethylene, including cross-linked polyethylene, is a thermoplastic, not a thermoset, although the cross-linking is commonly performed on the net shape parts, not the feedstock. For thermoset plastics, think melamine and Bakelite ; once molded into a shape and cured, they can't be re-molded.

Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
EPM is even more prevalent as an insulator for high-voltage cables (usually referred as HEPR - Hard grade Ethylene Propylene Rubber) since it has improved insulative characteristics over more traditional cables, such as cross-linked polyethylene, enabling a smaller cross sectional area for the same load carrying capacity.
