Flexible Polyimide Foam (ZTS-PI-FS) Description
Flexible Polyimide Foam (ZTS-PI-FS) is a material developed for use in extreme environments. It operates reliably over a temperature range from approximately –40°C to 150°C and conforms to recognised flame retardancy standards (e.g. EN 13501-2). The foam has measured radiation shielding properties, chemical corrosion resistance and maintains its compressive strength over prolonged periods. Consequently, it is suitable for use in aerospace, aviation, marine, transportation and construction sectors.
