Product Overview
Description
    Parker Chomerics SOFT-SHIELD® 4850 series multiplanar, conductive, Z axis foam consist of silver-plated fibers embedded into low density open cell urethane foam and provide stable electrical performance as well as superb z-axis conductivity with extremely short ground paths. The optimized conductive fiber construction allows for exceptional physical and mechanical properties. Manufactured in rolls, SOFT-SHIELD® 4850 can be easily die cut or slit into rectangular/square strip gasket seals.

    SOFT-SHIELD® 4850-STRIP consists of SOFT-SHIELD® 4850 in pre-cut strips that are ready to apply and ideal for quick install applications.

    Features and Benefits:
    • UL 94 V-0 flammability rating
    • Excellent through resistance (< 30 milliohm at 25% gasket deflection)
    • Option of uniform electrically conductive (silver-plated copper) acrylic pressure sensitive adhesive (PSA)
    • Excellent compression set properties
    • Very low closure force
    • Non-Nickel bearing material
    • Non-Bromine bearing material (silver plated materials)
    • ROHS compliant
    • Roll form compatible with high speed/low cost part conversion
    • Compartmental shielding or easy “peel-and-stick” grounding applications
