Tefzel™ is a modified ETFE (ethylene-tetrafluoroethylene) fluoroplastic . Tefzel™ ETFE resin combines superior mechanical toughness with an outstanding chemical resistance .Tefzel™ features high-energy radiation resistance. Most grades are rated for continuous exposure at 150°C (302°F). Superior anti-stick and low frictional properties makes it a superior contender among chemical corrosion coatings it also contributes in high resistance to impact and tearing.
Tefzel™ ETFE film is chemically inert and solvent resistant to virtually all chemicals, except molten alkali metals, gaseous fluorine, and certain complex halogenated compounds, such as chlorine trifluoride at elevated temperatures and pressures.
It also has low permeability to liquids, gases, moisture and organic vapors.
