PTFE
PTFE, a fluorinated polymer with exceptional properties, is one of the engineering plastics that DEMGY transforms and manufactures for its customers' needs.
PTFE: a high performance plastic material with exceptional properties
Known to the general public as Teflon ®, PTFE has many properties that are very useful in very demanding industrial sectors.
Non-toxic, UV-resistant and non-flammable, this high-performance thermoplastic is resistant to moisture and to attack by the active ingredients of certain chemicals. With a low coefficient of friction, it ages very well and maintains good dimensional stability over a wide temperature range from -80°C to 250°C.
It is possible to optimize the properties of PTFE by adding other materials: this is called filled PTFE. Fiber-filled PTFE is, for example, recommended for increased resistance to wear and chemical attack.
If you are looking for a material that is resistant to both wear and compression, graphite-filled PTFE is a good choice. If you need a material with good thermal conductivity and excellent resistance to deformation, you should choose carbon-filled PTFE. Finally, we recommend bronze-filled PTFE for a material with high thermal conductivity and high compression and wear resistance.
