Polybenzimidazole (PBI) polymers are known for their outstanding thermal and chemical stability. PBI is now available in molded form. The physical and thermal properties of this material are described. The chemical resistance of molded PBI, which was evaluated after immersion in a wide range of materials at various temperatures for up to 30 days, is also described. Molded PBI offers excellent resistance to most of the chemicals tested. Exceptions are hot solvents for the base polymer and hot aqueous strong acids. No effect was observed upon exposure to common oil and gas production environments. The excellent chemical and thermal resistance of molded PBI was confirmed in actual field trials.
