PFA

Polyfluor is known as both a PTFE specialist and also as a leader in PFA. PTFE is milky white in colour, while PFA (film and tubing) is transparent with a light blue glow. Because Polyfluor seeks to provide a specific solution for every need, we change and continuously develop to ensure we meet every challenge that customers bring to us.

What is PFA (Perfluoro Alkoxy)?

PFA combines the many positive properties of both PTFE and FEP. This polymer is primarily used when a material requires high flexibility, thermoplastic processability, weldability, and suitability for extrusion, injection moulding, or transfer moulding, as well as a higher continuous service temperature.

Product Specifications

Polyfluor offers PFA products with a lower melting temperature than PTFE and are also chemically inert and have a very low dielectric constant, which makes it insulating. Further, it has very low friction. PFA from Polyfluor also has the following properties:

  • Lower melting temperature than PTFE
  • Transparent/clear
  • Low dielectric constant (insulating)
  • Chemically inert
  • Very low co-efficient of friction
  • Antistick properties
  • UV resistant (resistant to sunlight and does not age)
  • Not hygroscopic (water absorption <0.01%)
  • FDA approved
  • Working temperature from -200°C to +260°C

Frequently Asked Questions (FAQ)

What is PFA and how does it differ from PTFE and FEP?

PFA (perfluoroalkoxy) is a high-performance fluoropolymer similar to PTFE, but with lower viscosity during processing. As a result, PFA is thermoplastically processable, whereas PTFE is not. Compared with FEP, PFA offers higher temperature resistance and better chemical resistance. It combines PTFE’s non-stick behaviour, low coefficient of friction and excellent electrical properties with the processability of a thermoplastic.

What temperature and chemical exposure can PFA withstand?

PFA can be used continuously at temperatures up to approximately +260°C, and temporarily even higher depending on the application. The material is fully resistant to virtually all chemicals, including strong acids, bases, solvents and corrosive gases. Unlike many other plastics, PFA retains its structural properties under extreme temperatures and in highly aggressive chemical environments.

Is PFA suitable for applications in the food, semiconductor or pharmaceutical industries?

Yes. PFA is highly suitable for ultra-clean applications. The material is chemically inert, has extremely low adhesion and is easy to clean. For this reason, it is widely used in food-safe systems, semiconductor manufacturing, pharmaceutical process installations and applications requiring very high-purity fluid handling. PFA can also be supplied in grades that comply with FDA and EU regulations, depending on supplier and product.

In which sectors or applications is PFA most commonly used?

PFA is used in environments where chemical exposure, high temperatures and absolute reliability are essential. Typical examples include:

  • Hoses, tubing and piping systems for aggressive media
  • Lining of tanks, reactors and pump components
  • Insulation material for high-performance cables
  • Components for semiconductor and clean-room processes
  • Laboratory and analytical equipment

The material performs exceptionally well where conventional plastics fail.

What are the advantages of PFA, and are there any drawbacks?

Key advantages of PFA include:

  • Usable at exceptionally high temperatures (up to approx. 260°C)
  • Fully chemically inert
  • Low coefficient of friction and excellent non-stick properties
  • High electrical insulating value
  • More transparent than PTFE, making it suitable for visual flow control

Weaknesses or points of attention include:

  • Higher material costs than standard plastics
  • Less wear-resistant than certain engineering plastics (such as PEEK)
  • Specialised expertise required for optimal processing and joining techniques
