Tefzel / ETFE

GENERAL DESCRIPTION

Tefzel ® ETFE is a fluorocarbon-based polymer. ETFE is an abbreviation for the chemical name Ethylene TetraFluoroEthylene. and 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, electrical and thermal insulation.

GENERAL PROPERTIES

Tefzel ® ETFE offers high purity, excellent chemical resistance, good permeability resistance, and excellent abrasion resistance over a temperature range of -300°F to +300°F (-185°C to +150°C). Tefzel ® ETFE is available in sheet, rod and film forms.
