Crosslinked polyethylene (PEX) was first prepared in the 1930’s by irradiating the extruded tube with an electron beam. Since its initial introduction, PEX has become increasingly popular in the construction industry. In the last few decades, the manufacturing process has improved significantly.
PEX Piping is a type of plumbing pipe made from high-density polyethelene. It is used mainly for residential and commercial plumbing applications, but it also used in commercial radiant heating and cooling systems on a large scale.
