Ethylene - tetrafluoroethylene copolymer, referred to as ETFE, has good mechanical properties, weather resistance, flame retardant, gas barrier and chemical resistance, etc., is one of the strongest fluorine plastics. In addition to the excellent properties of other fluorinated resins, it also has the characteristics of radiation resistance, strong adhesion to metal surfaces, and lighter than other fluorinated materials. ETFE products are divided into powder and particle two forms, can be electrostatic spraying or roll coating, extrusion, injection molding and other processing technology, to anti-corrosion lining, film, hose, cable and other forming parts, widely used in agriculture, construction, electronics, automotive and many other fields.
