Ratings Code:
G – Good to excellent. Little or no swelling, tensile or surface changes. Preferred
choice.
L – Marginal or conditional. Noticeable effects but not necessarily indicating lack of
serviceability. Further testing suggested for specific application. Very long-term
effects such as stiffening or potential for crazing should be evaluated.
P – Poor or unsatisfactory. Not recommended without extensive and realistic testing.
— – Indicates that this was not tested.
# – For fluoropolymer. Indicates good chemical resistance but potential for excessive
permeation.
