ETFE Detailed Properties
|
|
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.
