Grade: DuPont™ Kapton® FPC
Formula: PI
Form: Disk
Material: Polyimide (PI)
CAS Number: 60842-76-4
Commodity: Polymers
The DuPont™ Kapton® FPC PI Disk comes in 45 variations that differ in diameter, thickness, and tolerance. These polyimide disks have high heat resistance, chemical inertness and dielectric strength. Its properties make it ideal for applications in electrical insulation, thermal insulation and high-temperature electronics. The range of sizes and tolerances we offer allow Kapton® FPC disks to be customized for use as washers, spacers, and other components across electronics, aerospace, and industrial sectors.
