A growing number of standard profiles and sizes provide flexibility when selecting a gasket for a specific application. Custom profiles or sizes can also be produced. Each SOFT-SIELD 5000 Series gasket consists of an electrically conductive fabric jacket over a highly compressible urethane foam core. The nickel-plated, woven nylon rip-stop jacket is selfterminating when cut. Chosen for its excellent compressibility, the foam core typically requires less than lb/in (0.75 N/mm) closure force, making it especially useful for thin-walled plastic enclosures. Standard pressure-sensitive adhesive attachment tape (PSA) makes SOFT-SIELD 5000 Series gaskets a user-friendly and cost-effective design solution. Every profile in the SOFT-SIELD 5000 Series can be provided in a General Duty version or a UL 94V-0 rated version, as needed, with no difference in performance. FEATURES Choice of General Duty or UL 94V-0 rated versions Typically require < lb/in (0.75 N/mm) closure force 5 times lower than other gaskets >90 db attenuation from 0 Mz to 0 Gz Asymmetrical profiles, as well as C, V, P, D shapes No performance degradation after 0,000 compression cycles ide release liner for easy removal Kiss-cut parts on release sheets for easy peel-and-stick grounding applications Self-terminating jacket no sharp edges Tested to Bellcore GR-64-Core Airborne Contaminants requirements Custom lengths, custom profiles BENEFITS Cost-effective Alternative to BeCu fingerstock Pick and place installation Technical application support Global distributor/fabricator network Application-ready custom parts (die-cut, spliced, etc.) ith an extensive choice of profiles and sizes, SOFT-SIELD Gaskets are supplied as strips or kiss-cut parts on film release backers, or individual pre-cut pieces. Pressure-sensitive adhesive is standard. Single-piece picture frame gaskets also can be fabricated from continuous lengths, incorporating integral pre-cut notches for fasteners. (See page.) CONFIGURATIONS Gaskets are supplied in standard 8-foot lengths or cut-to-length strips. Depending on the profile, gasketing can also be supplied on spools. For rapid peel-and-stick grounding applications, the material is supplied as kiss-cut parts on polyester film release backers, or as individual pieces. Chomerics also fabricates single-piece, spliced picture frame gaskets from continuous lengths. ith their fully jacketed surfaces, these gaskets are ideally suited for low closure force applications that require 60 EMI shielding, or the ease of installing a onepiece gasket (see next page). Chomerics Applications Engineering department welcomes the opportunity to provide assistance with design and prototype fabrication of SOFT-SIELD 5000 Series EMI Gaskets in custom profiles. continued
