Ethylene Tetrafluoroethylene (ETFE)

Advantages

• High impact resistance
• Chemical resistance
• Excellent stress-crack resistance

Limitations

• Cost

Overview

Ethylene tetrafluoroethylene (ETFE) is essentially an alternating copolymer consisting of ethylene and tetrafluoroethylene segments. This a tough material with high impact resistance and useful mechanical properties up to near 350 degrees F (177 degrees C).

Its chemical resistance, electrical properties, and weathering resistance properties approach those of fully fluorinated polymers. Applications include components of pumps, valves, and other chemical process equipment; tie wraps; and electrical components.
