SOFT-SHIELD® 4850 Multi-Planar Electrically Conductive Foam EMI Shielding Gaskets
■Parker Chomerics SOFT-SHIELD® 4850 is a true multi-planar, Z-axis electrically conductive foam for indoor applications. It is based on the unique integration of electrically conductive silver-plated fibers into a low-density urethane foam, providing for a performance-driven, costeffective EMI shielding solution. It offers greater EMI shielding performance from other SOFT-SHIELD products which may only consist of an electrically conductive jacket over traditional urethane foam.
■Through the optimization of conductive fiber construction, loading and dispersion within the foam matrix, SOFT-SHIELD 4850 provides superb Z-axis conductivity with extremely short ground paths. Since the integrity of the base foam is uncompromised, SOFT-SHIELD 4850 offers exceptional physical and mechanical properties.
■SOFT-SHIELD 4850 is flammability rated to UL 94 V-0 and is available in cut sheets, bulk rolls or custom die cut shapes. A uniform (silver plated, copper particle) electrically conductive acrylic pressure sensitive adhesive (PSA) is available on one side to help secure after installation.
●Product Features
■95 dB shielding effectiveness from 20 MHz to 10 GHz
■Low compression set of less than 15%
■Stable electrical performance (through resistance) after multiple closure cycles
■Excellent through resistance (< 30 milliohm @ 25% gasket deflection)
■Non-nickel bearing material (silver plated fibers)
■Available in cut sheets, bulk rolls or custom die cut shapes
■Z-axis conductivity allows compartmental shielding
■At low deflection (15%) demonstrates optimal electrical performance
■Offered with or without electrically conductive acrylic pressure sensitive adhesive (PSA)
■RoHS, REACH and UL 94 V-0 compliant
