Main features:
 - The tubes are obtained by extrusion, at the appropriate temperature, of a mixture of high density polyethylene and additives, such as stabilizers and antioxidants. Cross-linking is done during extrusion by the silane method.
 - The tubes are white - smooth, and are supplied in rolls or sticks.
 - The crosslinking gives the base polyethylene a better resistance to heat, which is why this tube is suitable for conducting hot water. With crosslinking, the mechanical properties are modified. Thus, the behavior of the action of the internal pressure is influenced by the crosslinking rate produced in the polyethylene.
 - Crosslinking improves the resistance of polyethylene to high temperatures.
 - This tube has a very small interior roughness which results in very low pressure losses.
