abbreviated as PFA, is a high-temperature resistant thermoplastic from the fluoropolymer family.
PFA is produced by the copolymerization of tetrafluoroethylene (TFE) and perfluoroalkoxyl fluoroethylene (PAVE).
Properties of PFA:
High temperature resistance:
PFA is extremely heat resistant and can be used continuously at temperatures of up to 260°C (500°F) without losing its structural properties.
Chemical resistance:
PFA shows excellent resistance to a wide range of chemicals, including acids, bases, solvents and other aggressive substances. This makes it suitable for applications in the chemical industry.
Low friction:
PFA has low friction, which makes it interesting for sliding and bearing applications.
Electrical insulation:
Due to its electrical insulation properties, PFA is used in the electrical industry for the manufacture of cable sheathing, insulators and other components.
Transparency:
PFA is transparent and offers good light transmission. This property makes it interesting for applications where good visibility is required.
Good workability:
PFA can be formed by various processing methods such as extrusion, injection molding and thermoforming, which enables its versatile application.
Applications of PFA:
PFA is used in various industries, including:
chemical industry:
pipelines, valves, pumps and fittings due to its high temperature resistance and chemical resistance.
Electrical and electronics industry:
cable sheathing, insulators and other electrical components due to its electrical insulation properties.
Food industry:
Due to its high purity and food compatibility, PFA is used in food processing.
Medical technology:
hoses, seals and other components due to its biocompatibility.
Thanks to its outstanding properties, PFA is a versatile plastic that is used in demanding technical applications .
