Resistance of PEEK

A: Very good resistance: PEEK may be used without rest-

rictions

B: Moderate resistance: PEEK may swell. PEEK may ge-

nerally be used, but may under some circumstances
have to be replaced after being used several times.

C: Poor resistance: PEEK deform. PEEK should be used

only to a limited extent. We recommend that the PEEK
be tested beforehand (softening or wetting the PEEK).
