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 to the
reagent. Depending on the plastic, the effect may be
crazing, cracking, loss of strength or discoloration.
Solvents may cause softening, swelling and permeation
losses with LDPE, HDPE, PP, PPCO and PMP. The
solvent effects on these five resins are normally
reversible; the part will usually return to its normal
condition after evaporation.
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.
