Aircraft Insulation

SOLIMIDE® polyimide foam was developed with U.S. government agency, NASA, for the Apollo spacecraft and has since been used by dozens of the world’s leading OEMs, including most major commercial aircraft manufacturers as aircraft insulation across a variety of applications. The lightweight, fire resistant, open cell foam provides excellent thermal and acoustic capabilities, is self-supporting, is effective across a wide temperature range and meets various industry and OEM specifications like FAR25.856, BMS8-300 and AIMS 04-14-004. This advanced aircraft insulation technology provides enhanced passenger safety, improved fuel efficiency, increased aircraft availability, greater acoustic comfort, and easier installation and maintenance. The performance enhancements result in a lower total cost of ownership for aircraft OEMs, passenger and cargo airline organizations, and maintenance, repair and overhaul service providers.
