Rifeng pex 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.Rifeng 5-layer pex pipe is made up of five layers: crosslinked polyethylene, adhesive, oxygen barrier, adhesive, crosslinked polyethylene. The layers of adhesive bind the two layers of crosslinked polyethylene to the central barrier layer by a thermal reaction. The barrier layer is right in the center, this preventing the pipe from being damaged by scratch and from reducing its performance due to the moisture.
