The PERT-EVOH multilayer pipe is a new PERT pipe with an EVOH oxygen barrier. The bonding layer is made from a functionalised polymer that indissolubly bonds the PERT to the outer EVOH layer. The latter guarantees oxygen impermeability and fulfils the requirements of DIN 4726, preventing the diffusion of oxygen into heating systems.
