Multilayer tubes and pipes

Orevac® extrudable adhesives resins are used to provide the most reliable and highest quality bonding of:

  • PE materials towards metals or polar materials for coextruded multilayer barrier and composite pipe applications.
  • Up to 90°C, Orevac® resins gives superior bonding, offering greater reliability and a longer services life for hot water uses.

The structure PEX / Aluminium or EVOH are suitable for floor heating tubes which prevent the oxidation of heating equipment. Specific Orevac® adhesive resins have been designed to reach high adhesion levels between PEX and EVOH or Aluminium and are suitable for the tube extrusion process.

 

The coextrusion of heating pipes with an Orevac® tie layer and a layer of EVOH makes it possible to reduce the diffusion of oxygen into the heating circuits, thus drastically reducing corrosion. In addition to their excellent adhesion, Orevac® polymers offer suitable heat resistance, providing a long heating tube life.

Recommended Orevac® tie layer grades:
18334 18410/18410P
Recommended Orevac® tie layer Terpolymers grades:
9318

Grades are chosen upon the targeted properties.
