ECTFE
(ethylene-chlorotriflouroethylene)
Download Product Brochure (pdf) 

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.
