While difficult to bond to, with the use of Reynolds proper abrading and coating preparations an excellent silastic bond is possible. Additionally, FEP insulation, being a harder material than silicone rubber, is not prone to pin-holing and high voltage punch-thru when the cable surface is abraded or when strands break during in-field service. FEP is also more resistant to damage when making contact with sharp edges.

FEP cable should not only be considered for use in cable assemblies, but as high voltage hookup wire within encapsulated high voltage power supplies, TWTs and transformers.

Low DC corona inception, particularly after numerous temperature cycles, is another advantage of FEP over silicone cables. Teflon tape wrapped cable, which is similar to FEP in dielectric strength and corona inception, is difficult to bond to because of its multiple spiral cross section, irregular surface and variations in diameter
