Pipes from PEX-A are universal (as they can be used both for heating and for water supply) and are made of high density polyethylene, cross-linked with hydrogen peroxide. The reaction of the cross-linking happens in the extruder during the formation of the tube. The cross-linking procedure allows to get uniform transverse connections on all the thickness of wall even if it is heavy wall tube.
The molecules of polyethylene are combined into a three-dimensional structure. As a result of this process, such properties of the material as heat resistance, resistance to high pressure, impact strength at low temperatures and resistance to cracking at a voltage improve.
Oxygen barrier is made of ethylene-vinyl alcohol - a polymer with the best protective characteristics. Requirements to the standards DBN V.2.5.- 67: 2013 in relation to oxygen barrier property are largely overfulfilled. In addition, the adhesive layer between the pipe and the barrier layer provides a firm bond. The layer of ethylene-vinyl alcohol is insoluble in water and has a significant reserve of density in relation to resistance to abrasion and resistance to atmospheric influences, which increases the resistance of the pipe in harsh conditions at the construction.
