DuPont™ Kapton® FWR is a heat fusible polyimide-FEP fluoropolymer composite film that has a unique balance of excellent electrical, thermal durability, and chemical resistance properties. The properties of Kapton® FWR will provide a tough, high dielectric strength insulation with significantly improved hydrolysis resistance compared to other commonly used polyimide materials.
Kapton® FWR can be properly processed on most tape wrapping machines. It can be fused using either induction or radiant heat. Kapton® FWR films have a higher modulus and lower water vapor permeability than equivalent Kapton® FN films. The wire wrapping and sealing process may have to be modified to compensate for these differences.
Kapton® 150FWR019 film is constructed of a 1.0 mil Kapton® polyimide film with 0.5 mil of FEP fluoropolymer on one side. Kapton® 200FWR919 film is constructed of a 1.0 mil Kapton® polyimide film with 0.5 mil of FEP fluoropolymer on each side.
