Crack-Resistant Rigid Polyimide Insulation Sheets
Even when subjected to heavy compression, these rigid polyimide sheets won't crack. To use outdoors, add metal jacketing.
Sheets with a density of 12 lbs./cu. ft. are easier to cut than denser polyimide insulation sheets, which makes them good for die-punching applications. They are not, however, good for machining.
Sheets with a density of 60 lbs./cu. ft. are more durable than less dense polyimide insulation sheets, so they can stand up to machining. They’re often used for mold bases or press insulation.

Lightweight High-Temperature Polyimide Foam Sheets
In addition to being lighter in weight than silicone foam, this polyimide foam also remains soft and conformable across a broader temperature range. This foam has open-cell construction, which allows water, air, and gases to be absorbed.
- Color: Yellow
- Temperature Range: -300° to 400° F
- Cell Type: Open
- For Use Outdoors: No
- Density: 0.4 lbs./cu. ft.
- Pressure to Compress 25%: 1.3 psi (Ultra Soft)
- Tensile Strength Rating: Fair
- Oil-Resistance Rating: Not Rated
Flame-Retardant Sound-Absorbing Sheets
This insulation meets UL 94HF1 for flame retardance and ASTM E84 25/50 for flame and smoke. Use to quiet noisy areas and line machine enclosures. Sheets are made of polyimide foam.
