ETFE PELLET
Ethylene-tetrafluoroethylene, also known as ETFE, is one of the strongest fluorine plastics with good mechanical properties, weather resistance, flame retardant, gas barrier properties and chemical resistance. In addition to the similar properties like other fluorine resins, it also shows good radiation resistance, strong adhesion with metal surface, and is lighter than other fluorinated materials.
