What are ‘Fluoropolymers’ and What are their Common Attributes

By Dave Biering on June 12, 2018

The first fluoropolymer was polytetrafluoroethylene, better known by its abbreviation, PTFE

First, a definition: fluoropolymers are a family of plastic resins which are based on fluorine/carbon bonding. The family of products is varied through a manipulation of that bond by adding or subtracting fluorine through other bonds such as chlorine, ethylenes and other chemical agents.

The first fluoropolymer was polytetrafluoroethylene, better known by its abbreviation, PTFE, and by its brand name “Teflon.” It was discovered accidentally by a scientist at DuPont in 1938.

Fluoropolymers are strong, lightweight, and durable. They can also resist heat, water, salt and chemicals and do very well in demanding environments.

PTFE (which is the only fluoropolymer which does not melt) is processed through press and sinter techniques while the other common fluoropolymers (FEP, PVDF, PCTFE, PFA and a few others) are melt-processible. This means they can be compression and injection molded as well.

Fluoropolymers come in several forms:

  • Granulate
  • Melt-processable
  • Films
  • Paste
  • Dispersions

As with anything, there are both positives and negatives to fluoropolymers:

Positive attributes:

  • Chemically inert (with few exceptions)
  • Broad temperature ranges
  • Low friction
  • Excellent dielectric properties
  • Good thermal insulation
  • Good wear properties (with certain additives)

And on the negative side:

  • Cost (they can be expensive)
  • Processability – grades establish which method is used
  • Cold flow with some grades
  • High expansion rates

Typical applications for fluoropolymers are in electrical and electronics, pipe and chemical processing.

Fluoropolymers are an extremely diverse family of plastics and this blog post really just scratches the surface. For a deeper dive into the topic, watch our video (below).

If you think a fluoropolymer is the right fit for your application, we can help you choose the right one.

What is a fluoropolymer?

By Dave Biering on November 13, 2012

This is a question that often appears on our Ask the Experts form.  In fact, we’ve produced a fluoropolymer video (at right) to help you compare and contrast the different materials.  Fluoropolymers are a family of materials that are based on an atomic structure around fluorine carbon.  Different variations can be formulated by adding or subtracting fluorine through other bonds such as chlorine, ethylenes and other chemical agents.

Fluoropolymers come in several forms:

  • Granulate
  • Melt-processable
  • Films
  • Paste
  • Dispersions

Fluoropolymers are lightweight and durable, and resist heat, moisture and chemicals.  To learn more about the varieties available and different processing techniques, watch our video or contact our technical team for more information.
