Tefzel® ETFE is a fluorocarbon-based polymer known as its chemical name Ethylene TetrafluoroEthylene. The Tefzel ® brand of ETFE is manufactured only by DuPont. This material was introduced to provide a material with both corrosion resistance and mechanical strength over a wide temperature range. The fluoroplastic family offers plastics with high chemical resistance, low and high temperature capability, resistance to weathering, low friction, and electrical and thermal insulation. Tefzel ® ETFE is available in sheet, rod and film forms. It is also available in a fabric-backed sheet for construction of dual laminate vessels or the lining of existing chemical vessels.
