What is PFA coating?
PFA – perfluoroalkoxy - is a co-polymer product of PTFE.
The key advantage of PFA is its melt processability. This means that when cured, the constituents flow into one another, therefore the level of porosity at the surface of the cured coating is significantly reduced. This makes PFA almost impervious to all forms of Chemical attack, even at elevated temperatures up to 260˚C/500˚F.
PFA coatings can be built up significantly thicker than some other fluoropolymers – up to 1mm being achievable.
PFA also offers greater toughness/abrasion resistance than PTFE and FEP.
Key features:
- Wide temperature range (-190°C- +260°C)
- Good Cryogenic Stability
- High Electrical resistance
- High Impact resistance
- Resistant to nearly all chemicals, even at elevated temperatures
- Non-stick properties
- Thicknesses of 1,000 microns/1mm achievable
- Greater toughness than PTFE and FEP
- FDA Compliant
Typical applications include:
- Pumps
- Valves
- Industrial bakeware
- Dough hoppers
- Chemical vessels
