Parker Chomerics SOFT-SHIELD® 4850 Conductive Foam EMI Gaskets
Parker Chomerics SOFT-SHIELD® 4850 Foam EMI Gaskets feature true multiplanar, Z-axis electrically conductive foam for indoor applications. The gasket construction centers around the unique integration of electrically conductive silver-plated nylon fibers into a low-density urethane foam. This design results in a performance-driven, cost-effective EMI shielding solution. By optimizing the conductive fiber construction, loading, and dispersion within the foam matrix, the SOFT-SHIELD 4850 delivers excellent Z-axis electrical conductivity with extremely short ground paths. Parker Chomerics SOFT-SHIELD 4850 Electrically Conductive Foam EMI Gaskets offer a UL 94V-0 flammability rating and RoHS/REACH compliance. These gaskets are available with or without adhesive to fit various application needs.
