Chemische Beständigkeit PTFE
PTFE wird durch einige Alkalimetalle (geschmolzen oder in Lösung) und seltene Fluorverbindungen bei hohen Temperaturen und/oder Druck beeinflusst. Einige organische halogenierte Lösemittel werden absorbiert, wodurch geringfügige Formveränderungen verursacht werden, aber diese Effekte sind physisch und auch reversibel.
Legenda
R – Resistant/Beständig
LR – Limited Resistance/Beschränkter Widerstand
NR – Not recommended/Nicht empfohlen
ND – No Data/Keine Daten
Eigenschaften können durch das Verarbeitungsverfahren, den Verbindungstypen, extrudierte Abmaße und andere Variablen verändert werden. Es ist die Verantwortung des Endverbrauchers, die Eignung des Produkts für seine spezifische Anwendung vollständig zu testen.
