Crosslinked polyethylene (PEX) is a type of polyethylene which has undergone crosslinking in order to improve certain properties and particularly resistance to high temperatures which allows the use of PEX in a heating network.
PEX-a, with exceptional qualities, offers remarkable reliability.
First, PEX-a has great flexibility in every direction. Second, it is weather-resistant and can return to its normal form even at -40°C (-40°F). Thirdly, it is easy with the appropriate instrument to restore a pipe that has been deformed by crushing.
The advantageous mechanical properties of PEX-a significantly exceed those of PEX-b at all levels.
