Chemische resistentie PFA
PFA heeft als voordeel een hogere continue gebruikstemperatuur aan te kunnen ten opzichte van FEP. Tevens kan PFA op langere continue lengtes geëxtrudeerd worden dan PTFE.
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.
