Chemische resistentie PEEK

PEEK wordt over het algemeen beschouwd als één van de best presterende thermoplasten in de wereld. PEEK biedt uitzonderlijke prestaties over een breed scala van temperaturen en extreme omstandigheden.

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.
