JP Formable Polyimide Film
Description:
JP Formable Polyimide Films (e.g. Kapton JP, JPB Film) have been designed to give optimum forming characteristics. Polyimide films for forming have higher elongations at elevated temperatures while maintaining the combination of excellent physical, electrical, and mechanical properties inherent in HN and HA. The films polymer properties enable drawing deeper parts at lower temperatures 280¡ãC~300¡ãC and shorter cycle times. After forming, parts exhibit excellent shape retention and minimum shrinkage.
Application:
Parts may be formed from JP Polyimide Films that were previously difficult or impossible to form with HN:
• Diaphragms for automotive and heating and ventilating sensors and switches
• Speaker cones, domes, spiders, and surrounds
• Other applications including appliances, electronics, and aerospace
