ETFE rod is a type of rod made from “ethylene-tetrafluoroethylene copolymer”, which is a copolymer of ethylene and tetrafluoroethylene. It is a tough fluoroplastic with excellent chemical resistance, heat resistance, high mechanical strength, outstanding radiation resistance, weather resistance, and good electrical insulation properties. ETFE rods can be used in load-bearing applications under various harsh environments, such as in the aerospace, electronics, chemical, biomedical, and construction fields.
