Resilient. Durable. Impressive.
PTFE (polytetrafluoroethylene), known under the brand names Teflon, DyneonTMHostaflon and Fluon®, is essentially characterised by excellent chemical resistance, high thermal load and good sliding and insulating properties.
PFA (perfluoroalkoxy copolymer) and FEP (perfluoroethylene propylene) – thermoplastic fluoroplastics – are used as linings or coatings for metal parts and achieve corrosion protection comparable to PTFE.
A comprehensive package of partially fluorinated materials rounds off the processing options.
Among engineering plastics, the prominent position of PTFE is undisputed due to its outstanding material properties. If high resistance to chemicals (acids, alkalis and organic compounds) is required in a wide temperature range, practice shows that even high-quality steels and special metals (e.g. titanium and tantalum) can only be used with certain restrictions in terms of their resistance.
