PFA (Perfluoroalkoxy) film is a high-performance fluoropolymer film made from a copolymer of tetrafluoroethylene (TFE) and perfluoroalkyl vinyl ether (PAVE). It combines the best properties of PTFE (heat resistance, chemical inertness) and FEP (melt-processability, clarity), making it ideal for extreme environments where transparency, flexibility, and durability are critical. PFA film is used in high-purity semiconductor liners, chemical-resistant lab equipment, medical device coatings, and food-grade packaging due to its extreme chemical resistance, high-temperature stability, optical clarity, and heat-sealability.
Feature
Extreme Temperature Resistance
- Continuous use: -200°C to +260°C (-328°F to +500°F) - Short-term peak: Up to +300°C (572°F)
Chemical Resistance
- Resists virtually all acids, bases, and solvents (even stronger than FEP)
Optically Clear
- High light transmission (~95% visible light), similar to FEP but more thermally stable
Non-Stick & Low Friction
- Superior release properties for molding and industrial processes.
Flexible & Durable
- Retains toughness even at cryogenic temperatures.
Heat-Sealable & Weldable
- Unlike PTFE, PFA can be thermally bonded like FEP.
UV & Weather Resistant
- Stable under long-term sunlight exposure.
Common Specifications
Thickness: 0.025mm (1 mil) to 2mm (80 mils)
Width: Up to 1.5m (59") in rolls or sheets
