Chemfilm® DF2000 series combines fluoropolymers offering the highest temperature rating and the best electrical properties with the mechanical integrity and dielectric strength of polyimide film. Heat sealable surfaces allow the tape to be sealed to itself and other layers of fluoropolymer tape wrap insulation at regular wire processing temperatures. The fully sintered fluoropolymer base resin enables the films to be wrapped directly over the conductor.
Test programs in both military and commercial aircraft markets indicate the benefits of a proper ratio between fluoropolymer and polyimide for maximum protection against arc propagation and failure.
