MFR 20.1-24.0 ETFE Resin Granule SF-4027 For Cable Insulation
ETFE Pellet for Molding SF-4027 with MFR 20.1-24.0
Product Description
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.
