JP Formable Polyimide Films

 

Description:

JP Formable Polyimide Films (e.g. Kapton® JP, JPB Film) have been designed to give optimum forming characteristics. Formable polyimide films have higher elongations at elevated temperatures while maintaining the combination of excellent physical, electrical, and mechanical properties inherent in HN polyimide film. The films' polymer properties enable drawing deeper parts at lower temperatures 280°C~300°C and shorter cycle times. After forming, parts exhibit excellent shape retention and minimum shrinkage.

Characteristics

 • Excellent formability

 • Excellent shape retention

 • Good dimensional stability

 • Chemical resistance

 • Flame resistance UL V-0

 • High and low temp resistance

Application:

Parts that were previously difficult or impossible to form with HN may be formed from JP Polyimide Films:

• Diaphragms for automotive and heating and ventilating sensors and switches

• Speaker cones, domes, spiders, and surrounds

• Other applications including appliances, electronics, and aerospace
