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. Due to the crosslinking, the polyethylene’s performance is greatly enhanced still maintaining the excellent properties of thermoplastics.
