ETFE Detailed Properties

(Ethylene Tetrafluoroethylene)

The table below lists a generally accepted summary of properties that we believe to be reliable.   Please note that many of these resins are produced in several varieties and property characteristics may vary.  Therefore, determination of resin is dependent on the application and this table is only meant to serve as a general guideline.
