Chemische resistentie PCTFE

PCTFE wordt veel gebruikt in ruimtevaart toepassingen vanwege de extreem lage uitgaswaarde. PCTFE is ook ideaal voor cryogene toepassing. Producten van PCTFE hebben uitstekende fysische, mechanische en elektrische eigenschappen, vuurbestendig, chemische weerstand en lage vochtabsorptie.

Opmerking: De chemische weerstand van elk polymeer wordt grotendeels bepaald door de chemische structuur van het materiaal en de sterkte van de zwakste schakel in deze structuur.

Legenda

R - Resistant/Resistent
LR - Limited Resistance/Gedeeltelijk resistent
NR - Not Recommended/Niet aangeraden
ND - No Data/Geen data

Feitelijke eigenschappen kunnen veranderen als gevolg van verwerkingsmethode, compound type, geëxtrudeerde afmetingen en andere variabelen. Het is de verantwoordelijkheid van de eindgebruiker om de geschiktheid volledig te testen voor de specifieke toepassing.
