Customer Value Proposition:
SOFT-SHIELD
®
2000 gaskets consist of
silver-plated nylon yarn knitted over a highly
compressible, thermoplastic EPDM foam
core. Through a special treatment process,
the yarn jacket is secured to the core. This
self terminating outer layer eliminates the
need for secondary termination efforts and
metal particle debris associated with the
cut ends of common wire mesh gaskets.
SOFT-SHIELD 2000 gaskets are designed
specifically for EMI shielding electronic
enclosures where weather sealing is not
a requirement. The low closure force
characteristic of SOFT-SHIELD 2000 gaskets
allows enclosures to be designed with
fewer fasteners and/or thinner panels.
Configurations:
Standard SOFTSHIELD 2000 gaskets include
both rectangular and D cross sections.
Gaskets are provided in bulk on spools or
cut to specified lengths. For attachment
to flanges or other mounting surfaces,
these gaskets are available with an acrylic
pressure-sensitive adhesive (PSA) option
for quick, efficient application. Gaskets can
also be produced as 4-corner spliced picture
frames.
