Made from HALAR® ethylene-chlorotrifluoroethylene resin, these products are virtually unaffected by most common corrosive chemicals. ECTFE products have excellent chemical and mechanical properties, impact strength, and a broad service use temperature. This polymer offers extremely low permeability to liquids, gases, and vapors. The following physical property information is based on typical values of the base HALAR 901 resin.

Halar® ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of properties for highly demanding industries.  It is widely used in anti-corrosion applications as a lining or in self-supporting constructions (piping). Its excellent fire resistance and chemical resistance properties in wire and cable applications. Halar® ECTFE offers purity, surface smoothness, chemical resistance, and fire resistance which are key characteristics in the semiconductor and photovoltaic markets.
