Chemical resistance and characteristics

Chemical resistance

Le PEEK offre une résistance chimique quasi universelle : excellente tenue aux acides concentrés, bases, solvants organiques, huiles et carburants. Seuls les acides forts oxydants (H2SO4 concentré, HNO3 fumant) et les solvants très polaires à chaud peuvent l'affecter.
