Everflon+ High rate foam fluoropolymers

Everflon+ chemically foamable fluoroplastic(FEP.PFA.ETFE) compounds enhance electrical performance, improve fire safety and extend material usage. And they foam at rates of 35% to 55% when produced on standard high-temperature extruders – without gas injection or nucleating concentrates.

Everflon+ fluoropolymer(FEP.PFA.ETFE) compounds were developed to insulate Category 5e, 6, 6e, 6A and 8 plenum cables, low-capacitance cables and coaxial cables. But they offer the same high-performance characteristics when used for crosswebs, tapes or cable fillers.

Everflon+ foamed fluoropastic(FEP.PFA.ETFE) pellets are UL recognized for plenum cable insulation (File No. QMTM2) and are especially suited for thin-wall insulation of 0.005″ (0.127 mm) to 0.015″ (0.381 mm). Thin-wall insulation previously was produced from solid FEP, but Everflon+ unique properties allow our customers to foam fluoropolymers in situations where it could not have been foamed in the past.

And because Everflon+ Foam fluoroplastic(FEP.PFA.ETFE) does not require gas injection, customers save the cost of purchasing and maintaining injection equipment.

For insulation with a thickness of 0.015″ (0.381 mm) to 0.060″ (1.524 mm), foaming rates of 55% or even higher can be achieved. Typical cell size of the foam on average is less than 0.001″ (0.025 mm) and cell size is uniform. Tube extrusion or pressure extrusion may be used for less critical high-speed applications, such as production of coaxial cable.
