Customer Value Proposition
Parker Chomerics SOFT-SHIELD
®
4850
is a true multi-planar, Z-axis electrically
conductive foam for indoor applications.
It is based on the unique integration
of electrically conductive silver-plated
fibers into a low-density urethane foam,
providing for a performance-driven, cost-
effective EMI shielding solution. It offers
greater EMI shielding performance from
other SOFT-SHIELD products which may
only consist of an electrically conductive
jacket over traditional urethane foam.
Through the optimization of conductive
fiber construction, loading and dispersion
within the foam matrix, SOFT-SHIELD
4850 provides superb Z-axis conductivity
with extremely short ground paths.
Since the integrity of the base foam is
uncompromised, SOFT-SHIELD 4850
offers exceptional physical and
mechanical properties.
SOFT-SHIELD 4850 is flammability
rated to UL 94 V-0 and is available in
cut sheets, bulk rolls or custom die cut
