(see page 2.) 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. with their fully jacketed surfaces, these gaskets are ideally suited for low closure force applications that require 360 emi shielding, or the ease of installing a one- piece gasket (see next page). chomerics applications engineering department welcomes the opportunity to provide assistance with design and prototype fabrication of soft-shield 5000 series emi gaskets in custom profiles. soft-shield ? 5000 series conductive jacket over foam emi gaskets continued knife-edge strips profile number height width inches (mm) inches (mm) 74007 0.106 (2.69) 0.445 (11.30) 18 16 14 12 10 8 6 4 2 0 0 5 10 15 35 20 25 30 deflection (%) compression (lbs/lin.inch) knife-edge profile w h 74007 table 9 inquiries are invited concerning other cross sections and sizes. typical cross section tolerances: 0.010 in.

(see page 2.) 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. with their fully jacketed surfaces, these gaskets are ideally suited for low closure force applications that require 360 emi shielding, or the ease of installing a one- piece gasket (see next page). chomerics applications engineering department welcomes the opportunity to provide assistance with design and prototype fabrication of soft-shield 5000 series emi gaskets in custom profiles. soft-shield ? 5000 series conductive jacket over foam emi gaskets continued knife-edge strips profile number height width inches (mm) inches (mm) 74007 0.106 (2.69) 0.445 (11.30) 18 16 14 12 10 8 6 4 2 0 0 5 10 15 35 20 25 30 deflection (%) compression (lbs/lin.inch) knife-edge profile w h 74007 table 9 inquiries are invited concerning other cross sections and sizes. typical cross section tolerances: 0.010 in.
