DuPont™ Kapton® CR Polyimide Film

Kapton® Type CR was developed to for high resistance to corona damage. It shows corona resistance greater than 100,000 hr at 50 HZ and provides twice the thermal conductivity of standard Kapton®.General Kapton® information: Kapton® is synthesized by polymerizing an aromatic dianhydride with an aromatic diamine. It has excellent chemical resistance; there are no known organic solvents for the film. It does not melt. It can be used at both high and low temperature extremes. Kapton® polyimide films can be used in a variety of electrical and electronic uses: wire and cable tapes, formed coil insulation, substrates for printed circuit boards, motor slot liners, magnet wire insulation, transformer and capacitor insulation, magnetic and pressure-sensitive tapes, and tubing.Data provided by DuPont High Performance Films.No detailed property information is available about this grade.
