Cross-linked polyethylene provides exceptional impact and stress cracking resistance which is the best choice for chemicals that happen to be recognized to become pressure cracking agents. Cross-joined tanks will also be considered the most suitable choice for sodium hypochlorite purposes.

However, the process normally takes marginally for a longer period than the other two approaches given that the polymer has to be stored at large temperature and pressure for very long durations during the extrusion course of action. The cross-joined bonds are between carbon atoms.
Capability to merge new PEX with present copper and PVC systems.
