Processing of this material can be done on most wire taping standard polyimide films.
DuPont™ Oasis® 120TWT561 is a heat sealable composite film that is made using DuPont high strength polyimide film and fluoropolymer designed to meet the light weight wire requirements of AS22759/80-92. 120TWT561 film has a unique balance of excellent electrical, thermal durability, and chemical resistance properties, including improved hydrolytic stability, that make it ideal for the next generation of aerospace wire designs.
120TWT561 film possesses excellent bonding characteristics to itself and to other fluoropolymer-containing materials, while providing low adhesion to metal conductors. These unique bonding characteristics should provide a wide operating window for producing modern composite wire insulations.
Applications
• Aerospace Wire and Cable
o Airframe wires
o Hookup wires
o General purpose aircraft wires
• Bonding
