APICAL is a ultra-heat-resistant polyimide film that has been developed through our own studies using a wealth of our unique high polymer technologies.
Skin
Foam
Application
Miniaturization and more advanced features of information and telecommunication devices.
Used in electronic materials such as those for cellular phones, HDD wireless suspensions, and optical pickups.
High Performance in Cutting-edge Technology
Used in materials for satellites and superconductor facilities by taking advantage of superior heat and low-temperature resistance and radiation-resistance characteristic
Insulating Coating Materials Used to Support the Social Infrastructure
Used as insulating coating material for wires, cables, motors, and power generators used for airplanes, railroad trains, and other critical applications
