PEXa EVOH Oxygen Barrier Pipe Production Machine
This line is used to produce 3 layer PEXa EVOH pipes (PEXa pipe-Adhesive-EVOH). PEXa EVOH pipe is produced in two step ways, firstly produced PEXa pipe, and then need another separate line to coat the adhesive layer and EVOH layer.
PEX-a EVOH Pipe: Suitable for underfloor heating systems and radiators.
Its manufactured by the peroxide xa cross-linking system. It has 3 layers: PEXa / adhesive / EVOH. The PEXa EVOH pipe has great flexibility and perfect homogenization of the cross-linking. It is very resistant to corrosion and chemical agents. It has an excellent thermal memory.
The EVOH barrier is a thin layer of ethyl vinyl alcohol that prevents the permeability of the pipe and diffusion of oxygen throught it. This avoids the corrosion of the metal parts, which prolongs the life of the whole installation.
Chemical resistance to building materials allows the PEXa EVOH pipe to be embeded in walls and floors without the need for protection.
