Axon’ Cable’s patented process
enables extruded PTFE to be applied
to a conductive copper core without
damaging the surface of the conductor.
This avoids oxidation and helps preserve
the qualities of copper to ensure good
connections.
Previously, a manufacturing process that
did not oxidise copper has only been
used with bare copper wires insulated
with silicone or thermoplastic insulating
materials such as perfluoroalkoxy (PFA).
The new Axon’ process provides a more
economical alternative to bare copper
wires insulated with PFA, as PTFE is
cheaper than PFA, while offering the
same heat performance. The other major
advantage of the process is that it does
not require silver or nickel-plating on
copper to protect the conductor from
oxidation.
PTFE not only offers good electrical
insulation, but it also affords very good
chemical resistance. PTFE is chemically
inert and self-extinguishing; it also resists
abrasion. Unlike thermoplastic materials
such as PFA, PTFE does not melt and
resists a soldering iron, even at 350°C.
PTFE also allows for very thin insulation
thicknesses compared to silicone
insulated wires.
PTFE-insulated bare copper wires are an
ideal solution for applications working
under 200°C, such as electrical appliances
(ovens, cooking plates and boiler burners,
for example) and automotive engines.
