The PERT EVOH 5 multilayer pipe consists of five layers: the two PERT layers (inner and outer) are bonded to the aluminium intermediate layer by two bonding layers of stabilised polymer. The EVOH layer provides an oxygen barrier, reduces linear thermal expansion effects and gives the pipe dimensional stability and flexural strength. The internal material (PERT) 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.
