The exterior of foamed wire insulation can be coated with a solid layer (jacket) of ETFE or ECTFE for wires used in telecommunications and fiber optics. This arrangement allows the foamed perfluoro-polymer to provide good electrical properties while the skin layer supplies sufficient mechanical properties. A foamed FEP wire insulation (eore), with a thickness of 0.5 mm, was coatedl with 51 pm of an ETFE jacket it had a dielectric constant of 1.64 and dielectric breakdown strength of 26.6 kV/mm. 

Electrical Properties. CeUular polymers have two important electrical appHcations (22). One takes advantage of the combination of inherent toughness and moisture resistance of polymers along with the decreased dielectric constant and dissipation factor of the foamed state to use ceUular polymers as electrical-wire insulation (97). The other combines the low dissipation factor and the rigidity of plastic foams in the constmction of radar domes. Polyurethane foams have been used as high voltage electrical insulation (213).
