Description

Thermalimide is a high performance bagging film for cure temperatures up to 426°C (799°F).

Benefits

• High temperature resistance enables vacuum bagging for extremely high temperature applications.
• Flexibility for applying pressure over simple contoured shapes.
• Superior toughness of film in comparison to metallic foils helps avoid bag tearing.
