DuPont™ Kapton® MT polyimide film is a homogeneous film possessing 3x the thermal conductivity and cut through strength of standard Kapton® HN. The Kapton® FMT polyimide film provides all the benefits of the Kapton® MT polyimide film with the addition of a fluoropolymer resin coated on both sides of the film.
Kapton® MT and Kapton® FMT offer an excellent combination of electrical properties, thermal conductivity and mechanical toughness for its use in electronic and automotive applications.
Kapton® MT and Kapton® FMT films have higher modulus than HN; this offers improved strength to the final product.
Applications include:
