SOFT-SHIELD 4000 materials are low-cost, low closure force EMI gaskets that provide high levels of shielding and grounding in commercial electronics. Rectangular profile SOFT-SHIELD 4000 Series gaskets feature a PORON® open cell urethane foam core wrapped with fabric-reinforced aluminum foil. The fabric/foil covering has no loose conductive fibers or sharp edges. All 4000 Series gaskets can be supplied with or without an electrically conductive, pressure-sensitive adhesive on one side for easy gasket attachment.
SOFT-SHIELD 4000 shielding materials are also available in continuously wrapped strips with 10 inch (25.4 cm) and 20 inch (50.8 cm) standard lengths. They can be supplied as cut-to-length parts, die-cut parts, and custom 360 ° wrapped die-cut parts. For rapid peel and stick grounding applications, the materials are available as kiss-cut parts on polyester film release sheets.
