* Mercury will permeate through all resins listed but only chemically attack    those resins not listed as EE.

Chemical Resistance Classifications

E = 30 days of constant exposure cause no damage. Plastic may even        tolerate for years.

G =  Little or no damage after 30 days of constant exposure to the reagent.

F = Some effect after 7 days of constant exposure. Depending on the plastic,       the effect may be crazing, cracking, loss of strength or discoloration.       Solvents may cause softening, swelling and/or permeation losses.

N = Not recommended for continuous use. Immediate damage may occur.       Depending on the plastic, the effect will be a more severe crazing,       cracking, loss of strength, discoloration, deformation, dissolution or       permeation loss. - = Not tested. Finger Lakes Extrusion recommends that       you test under your own conditions.

NOTE: The chemical resistance information in this chart is a general guide only. Because many factors can affect chemical resistance, you should test under your own conditions. If any doubt exists about specific applications contact us .
