ETFE / Ethylene TetraFluoroethylene

GENERAL DESCRIPTION
Tefzel ® ETFE is a fluorocarbon-based polymer. ETFE is an abbreviation for the 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 low friction, electrical and thermal insulation.
ETFE - Acronym for tetrafluoroethylene/ethylene copolymer.Has a high resistance to ageing and weathering, and has limited resistance to oils, grease and oxidizing acids. ETFE does not burn.

GENERAL PROPERTIES
Tefzel ® ETFE offers high purity, excellent chemical resistance, good permeability resistance, and excellent abrasion resistance over a temperature range of -185°C to +150°C (-301°F to +302°F). Tefzel ® ETFE is available by special order in sheet, rod and film forms.
