Hi-Flex™ Fabric-Over-Foam EMI Gaskets

Orbel’s EMI gaskets are ideal for a variety of applications including computers and telecommunications equipment

Image of Orbel Hi-Flex™ Fabric Over Foam EMI GasketsOrbel’s Hi-Flex fabric-over-foam EMI gaskets are ideal for controlling electromagnetic interference. These 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 flexible metalized gaskets are lightweight, self-terminating when cut, and exhibit low compression forces which make 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-profile gaskets are supplied with a double-sided pressure-sensitive adhesive for an easy and secure installation. We also perform many secondary modifications to our fabric over foam gaskets like cutting to length, kiss-cutting, clearance notching, and miter cutting for custom-frame style gaskets.
