ABSTRACT:
A multilayer polyimide-fluoropolymer insulation structure containing (a) a layer of a polyimide-fluoropolymer composite composed of a polyimide copolymer base layer, fluorinated ethylene-propylene (FEP) copolymer layers bonded to both sides of the polyimide copolymer base layer and a FEP-polytetrafluoroethylene (PTFE) blend layer bonded to at least one of the FEP layers and (b) an overlying layer of unsintered PTFE. The insulation structure has superior cut-through resistance when used in aerospace wire and cable applications.
