Product Description

25x3.5mm PEXa Oxygen barrier EVOH Pipe for Underfloor and Radiant HeatingPEX pipe is produced with crosslinked polyethylene. Crosslinking is obtained through a chemical process that increases the bonds between macromolecules to form a more complex structure than the normal polyethylene. Due to the crosslinking, the polyethylene's performance is greatly enhanced still maintaining the excellent properties of thermoplastics.

HEWAI PEX pipe is a ideal solution for underfloor heating system, it provides a superior, efficient & clean heating system by distributing heated water from a heart source through a piping network. The PEX heating pipe has excellent mechanical performances and the ability to withstand instand high temperature up to 110ºC. At the same time, HEWAI PEX pipes can be manufactured into coils up to 500 meters,with efficient & no-fuss installation.HEWAI PEX-a Pipe
