Customer Value Proposition
SOFT-SHIELD
®
3700
Plated-Fabric Wrapped Foam EMI Shielding
Gaskets for High Temperature Operation
The fabric is resistant to oxidation
thus delivering years of shielding and
electrical grounding.
SOFT-SHIELD 3700’s wrap around
technology grounds the gasket from
point to point, ultimately eliminating any
EMI gaps, and typically requires less
than 1 lb/in (0.175 N/mm) closure force,
making it effective for low-closure-
force applications.
SOFT-SHIELD 3700 takes less than
10% compression set, less than most
other fabric-over-foam EMI gaskets on
the market. This results in more reliable
and repeatable shielding performance,
is an excellent alternative shielding
solution to traditional spring finger
type products and makes this product
family one of the most versatile EMI FoF
products offered to the market.

Parker Chomerics SOFT-SHIELD
®
3700
fabric-over-foam (FoF) EMI shielding
gaskets are low-closure EMI shielding
gaskets for indoor applications. Available
in strip form, SOFT-SHIELD 3700
is designed to be used in elevated
temperature applications where
continuous operating temperatures of
125
o
C or less are required. SOFT-SHIELD
3700 is flammability rated to UL 94 V-0
and is available with rectangle or square
profile cross sections, each engineered
to optimize mechanical form, fit and
function while also optimizing electrical
performance.
By combining the shielding effectiveness
of an electrically conductive fabric along
with the conformability afforded by a foam
core construction, SOFT-SHIELD 3700
ensures both high shielding and reliability
for the life of the equipment.
It is offered exclusively in a nickel-plated
copper polyester woven RipStop fabric,
which is wrapped around silicone foam.
