Pex-Al-Pex Pipes

Multypexalfa is PEXb-Al-PEXb multilayer pipe, produced by Plastica Alfa for hydronic applications and hydraulic systems, guaranteeing outstanding performance thanks to the perfect combination of metal and plastic.
1. External layer
It is produced in PEXb and it protects the aluminium layer making it resistant to external agents (cement, abrasions, electrochemical attack).
2. Bonding layers
They are produced by a funzionalized polymer that strongly sticks the internal and external layer to the aluminium layer.
3. Middle layer
It is a pipe in aluminum alloy, longitudinally butt welded, that acts as oxygen barrier, reduces the effect of linear thermal expansion and gives the pipe shape stability and resistance to bending.
4. Internal layer
It is produced in PEXb and it gives to the pipe the resistance to high temperatures under pressure, while keeping unaffected the water potability.
