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.
