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.
