Hi-FlexTM Fabric Over Foam Gaskets
Orbel’s Hi-Flex™ Fabric Over Foam EMI Gaskets are
ideal for controlling electromagnetic interference. Our gaskets
are manufactured from a resilient open cell urethane foam
core with a durable high performance electrically conductive
copper-nickel plated nylon ripstop fabric. These exible metalized
gaskets are lightweight, self-terminating when cut and exhibit low
compression forces which makes them perfect for shielding
seams, doors and access panels.
Orbel offers over 100 standard EMI gaskets in a wide variety
of shapes and sizes to solve even the most challenging
EMI shielding application. All standard prole gaskets are
supplied with a double sided pressure sensitive adhesive for an easy and secure installation. We also perform many
secondary modications to our fabric over foam gaskets like cutting to length, kiss-cutting, clearance notching and miter
cutting for custom frame style gaskets.
Orbel also manufactures custom Fabric Over Foam I/O Backplane and D-subminiature gaskets fabricated to our customer’s
specic applications. These gaskets are constructed from a wide variety of thicknesses and die cut to accommodate the
custom cutout conguration.
