Fluoropolyimides
Key Benefits
High thermal stability (~ 500°C)
High glass transition temperature
Excellent optical transparency
Low moisture absorption
Good electrical insulation
Low dielectric constant
Resistance to photo-degradation
Solubility in polar solvents
Good flexibility
Good chemical resistance
Excellent creasable film forming properties
Fluoropolyimides (FPI) exhibit
exceptional high thermo-oxidative properties usually associated
with conventional aromatic polyimides. Attractive features like
high optical transparency, excellent dielectric characteristics,
and solubility in common polar solvents make these
fluoropolyimides unique class of polymers.
