Oxygen Barrier EVOH PA Nylon Pipe Production Line| PA Nylon Pipe Extrusion Line

This oxygen barrier pipe production line is used to produce 5 layer Polyamide PA oxygen barrier automobile fuel tubes. The inner and outer layer is PA 12 material, then two bonding layer, and middle EVOH oxygen barrier layer.
This multilayer PA fuel tubes are mady by co-extrusion technology, with 5 sets of extruders. EVOH (Ethylene-Vinyl Alcohol) materials are windely used in automotive applications in multi-layer fule lines owing to their excellent barrier properties to aromatic and aliphatic hydrocarbons. These barrier materials are essential to limit environmental fuel emissions and comply with the challenging requirements of fast changing internationak regulations.
