  • Description

The PEX-Al-PEX multilayer pipe belonging to the Multypexalfa line consists of 5 layers: the two PExb layers (inner and outer) are bonded to the aluminium intermediate layer by means of two stabilised polymer bonding layers. The aluminium layer provides an oxygen barrier, reduces linear thermal expansion effects and gives the tube dimensional stability and flexural strength. The internal material (PEXb) provides resistance to high temperatures under pressure while maintaining the potability characteristics of the water.

Produced in rolls of different sizes, it is ideal for underfloor heating and cooling systems and is widely used in compressed air systems, naval and industrial plants.
