• Thermal and acoustical insulation products fabricated from fire-resistant, lightweight polyimide foam.

  • Open-cell foam available as thermal and acoustical insulation for fuselage, bulkhead, cockpit, duct treatments, and pipe applications.

  • Claredense is a densified foam designed for use as headliner padding and carpet underlayments.


  • Headliner padding, carpet underlayments.

  • Aircraft bulkheads and fuselages requiring lightweight thermal and acoustic treatments.

  • Ducting where noise attenuation is needed.

  • Combined with vapor-barrier jacketing, it can be used in areas requiring moisture management.

  • May be used in areas requiring sound transmission-loss treatments when combined with Claremont’s Coustifab products.

  • Pipe insulation for potable water systems.


  • Lightweight polyimide foams offer densities as low as 0.33 PCF. This translates to increased payload and greater fuel efficiency.

  • Polyimide foam is inherently fire resistent; very low smoke developed; no significant toxic offgassing.

  • Extensive testing completed.

  • Numerous configurations available to meet specific needs including sheet, pipe covering, molded, densified, cut-to-shape, and bagged.

  • Numerous facings and jackets available including fiberglass cloth, MYLAR, aluminized MYLAR, KAPTON, and aluminum foil.

  • Polyimide foam is flexible and resilient from -300°F to +600°F.

  • Maintains integrity even after long-term vibration.

  • Improved habitability— Polyimide foam is non-fibrous and halogen free; no special handling is required.
