PFA is a fluoropolymer with a high degree of purity. It is melt-processable and can be used in a wide range of operating temperatures. PFA is highly resistant to chemicals, aging and climatic influences. A small friction coefficient testifies to the material’s nonstick properties.
PFA is a fluorocarbon in which the carbon atoms are fully bonded to the fluorine atoms. The fluorine-carbon bonds are the strongest known molecule bonds and explain the material’s chemical resistance. Other polymers and elastomers absorb different amounts of the materials that they come into contact with, and this applies to organic liquids in particular. Absorption with PFA is minimal and a reaction between PFA and the surrounding media is extremely rare. Permeation is closely linked to absorption. Besides PTFE, PFA offers the highest resistance to creep flow and it has good electric insulation.

1 Typical MFR ranges from the grade manufacturer’s technical data sheet, tested to ASTM D3307. They are guidance values, not product specifications. The listed standard packaging is the manufacturer’s packaging; grade availability, sample availability, minimum order quantity and lead time are confirmed against the individual requirement.
High-purity PFA for semiconductor applications
Convena offers PFA HP grades for high-purity applications. PFA and PTFE grades tested to SEMI F57 are available for semiconductor manufacturing environments where material purity, chemical resistance and consistent performance are critical.
Typical uses
Fluid-handling components, sealing solutions and other demanding parts used in semiconductor production environments.
Qualification support
Discuss contamination, extractables, grade selection and the documentation required for your qualification process with our team.
Conductive PFA
For a published conductive reference grade, NEOFLON™ PFA AP-230ASL has a typical MFR of 1.7 g/10 min and a typical volume resistivity of 1.0 × 107 Ω·cm (Daikin method). It is intended for extrusion applications and conductive valve linings. These are representative manufacturer values rather than a specification; confirm the current TDS and suitability for the end use before selection.
Recycled PFA / PIR PFA
For selected industrial applications, Convena can discuss recycled PFA and PIR PFA options. Available MFR range, colour, origin and application suitability depend on the individual material stream and are confirmed with the offer.
