Chemical Compatibility Quick Reference Chart Chemical Resistance Classification Resin Codes E 30 days of constant exposure causes no damage. Plastic ECTFE ETFE FEP FLPE FLPP HDPE LDPE PC PETG PFA PMMA PMP PP PPCO PPO PS PSF PUR PVC PVDF ResMer SAN TFE TPE XLPE 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.
