Material Notes:

Description: SOFT-SHIELD® 4850 represents the latest advancement in EMI shielding gaskets based on Multi-planar, Z-axis conductive foam technology. SS4850 is based on the unique integration of electrically conductive silver-plated fibers into a low density urethane foam providing the basis for a performance driven, cost effective EMI shielding solution.Typical Applications: Applicable for I/O panels, backplanes, connectors, access panels along with rectangular/ square strip gasket seals; Telecom infrastructure rack and enclosure components; Servers, desktop PCs; LCD/PDP large screen TV’s; Indoor electronics application requiring UL94 V-0 rating.Information provided by Chomerics
