FFKM
FFKM
FFKM (voorheen FFPM), ook bekend als perfluorelastomeer, is een familie van elastomeermaterialen met een volledig gefluoreerde polymeerstructuur en een fluorgehalte van meer dan 71%. Hierdoor behoren deze materialen tot de elastomeren met de hoogste chemische bestendigheid. FFKM presteert goed in uiteenlopende veeleisende omgevingen, zoals bij hete aminen, stoom, oplosmiddelen en koolwaterstoffen.
Afhankelijk van het type heeft FFKM ook de hoogste temperatuurbestendigheid die beschikbaar is voor elastomeermaterialen. Vooral de combinatie van hoge temperatuur- en chemische bestendigheid maakt FFKM tot een van de meest hoogwaardige elastomeren.
Tot voor kort hadden FFKM-polymeren een beperkte bestendigheid tegen lage temperaturen. Nieuwe polymeerchemie biedt nu FFKM-typen die hun afdichtende eigenschappen behouden bij temperaturen tot −40 °C.
FFKM is verkrijgbaar in verschillende uitvoeringen, die voornamelijk verschillen in de manier waarop ze zijn gevulkaniseerd.
