Chemische Beständigkeit PVDF
PVDF ist sehr geeignet für Anwendungen, die eine ausgezeichnete chemische Beständigkeit, eine hohe Reinheit und hervorragende mechanische Eigenschaften erfordern. PVDF wird oft als Beschichtung oder Schutzabdeckung bei Anwendungen in der chemischen Industrie verwendet.
Hinweis: Die chemische Beständigkeit von jedem Polymer wird hauptsächlich durch die chemische Struktur des Materials und die Stärke des schwächsten Glieds in dieser spezifischen Struktur bestimmt.
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.
