Chemical Resistance

A - No attack, possibly slight absorption. Negligible effect on mechanical properties.
B - Slight attack by absorption. Some swelling and a small reduction in mechanical properties likely.
C - Moderate attack of appreciable absorption. Material will have limited life.
D - Material will decompose or dissolve in a short time.
