“CP” PEEK Material Chemical Compatibility Chart

Ratings:

A = Excellent
B = Good – Minor Effect, slight corrosion or discoloration.
C = Fair – Moderate Effect, not recommended for continuous use. Softening, loss of strength, swelling may occur.
D = Severe Effect, not recommended for ANY use.
N/A = Information Not Available
