AFR-700B

Air Force Developed High Temperature Polyimide

AFR-700B is a high temperature polyimide capable of surviving long term exposure to temperatures up to 650°F (343°C). Over $1 million of data has been generated on AFR-700B by the Air Force and it is qualified for various military applications. AFR-700B can be processed into composites using prepreg or by solvent-assisted resin transfer molding (saRTM).
