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. |
