uniform coverage: The textile-like properties of ARACON
fibers contribute to extremely effective, uniform shield coverage. The
large number of very fine fibers,
together with the tendency of yarn bundles to flatten and spread, makes
it easy to obtain high coverage levels with reduced windowing.
Ease of pushback is maintained even at high coverage.
high-frequency shielding: The fine ARACON
fibers provide a very high surface-to-volume ratio. Together
with the excellent coverage, the extra surface yields improved
high-frequency EMI shield performance. For low frequencies, a
hybrid of metal wire and ARACON fibers
offers good performance with weight savings.
weight: In a typical case, switching to ARACON
fibers allowed a weight savings of 60% in the braid, which translated
to an overall reduction in cable weight of 26%. Weight
savings can be especially important in aerospace and similar
applications where every ounce counts.
Braid made from ARACON fibers has
successfully replaced copper braid in military applications where ease
of movement and durability were critical.
Yarns of ARACON fibers are fully
compatible with standard braiding equipment. Shields made
with ARACON fibers can be terminated by
soldering or with band straps.
