ABSTRACT:
Disclosed is a shaped body exhibiting good long-term thermal stability, comprising at least one fluorohydrocarbon polymer which can be processed by melting, and at least one heat-resistant thermoplastic polymer, wherein at least the fluorohydrocarbon polymer forms a phase which is coherent or at least largely coherent. The weight ratio of the fluorohydrocarbon polymer to the thermoplastic polymer preferably varies between about 80:20 and about 20:80. The shaped body is preferably a film used as a layer of insulation.
