FEP datasheet and FEP properties
Below you will find an overview of the properties of FEP, some examples where FEP is used for and the typical values of FEP in a FEP datasheet.
FEP properties
These properties of FEP make it a widely used material in a variety of different applications:
-
Negligible moisture absorption
-
Very low coefficient of friction
- Non-stick surface
-
Chemical resistant to almost all industrial chemicals and solvents
-
exceptional dielectric insulation properties
-
High crack resistance
-
Very low gas penetration
-
Wide temperature range -200 to + 204 ° C
-
Resistant to outside conditions such as UV, ozone and sunlight
-
Non-toxic, FDA approved
-
High transparency for both visual light and UV light up to 98%
