SOLIMIDE® is an environmentally friendly, non-toxic, low density, light weight, polyimide foam designed as a high performance thermal and acoustic insulator with a uniquely wide continuous temperature range from below -325°F(-200°C) up to +572°F (+300° C). When exposed to flame, SOLIMIDE® chars rather than burns, creating a burn barrier, will not propagate flame, and emits very little smoke and no toxic fumes. It is neither hydrophobic nor hydrophilic so it doesn’t wick liquid and will float atop resting water. SOLIMIDE® is basically inert and doesn’t outgas, is resistant to most petroleum chemicals, doesn’t support microbial growth, is non-toxic, and doesn’t significantly change size going from extreme cold to extreme heat. When used to insulate aircraft fuselage, aerostructures, the cockpit, cabin, and cargo bay, SOLIMIDE® improves passenger and crew safety while lightweighting the aircraft to improve fuel efficiency and progress to sustainability goals.
