Dupont™ Kapton® 120FWN616B is a multi-layer polyimide-fluoropolymer composite heat fusible film that has a unique
balance of excellent electrical, mechanical, thermal durability, and chemical resistance properties. The properties of
120FWN616B make it suitable for insulating copper conductor used in demanding magnet wire applications where good adhesion and dielectric properties are desired.
120FWN616B consists of a layer on 25 micron thick polyimide film between two layers of improved high temperature Teflon® fluoropolymer. Both fluoropolymer layers are approximately 3.8 microns thick.
