Tin/Copper EMI-Shielded Expandable Sleeving, Aramid Core

Flex-Shield is a high-performance, EMI shielding, expandable braid that is lightweight, flexible and is available with or without a ground. The fiber cores are made of high-temperature meta Aramid Fiber (Nomex) and are individually wrapped with a Tinned-Copper Foil. The fibers are braided together at a low braid angle to create a tubular product that can expand and contract to a limited degree for a perfect cable fit.

These foil-wrapped fibers create a sleeve that provides good EMI protection and yields a material with outstanding flex-life. This product is intended for high-flex, high-temperature, and environmentally tough applications.

Flex-Shield is currently in use on several aerospace applications where light weight and high performance are needed. The material meets UL1441, VW-1 (1/8 thru 3/4" sizes only) for flammability and has an operational temperature range of -40° to 150°C (-40° to 302°F).
