ISO J 213 is an electromagnetic shielding gasket designed to limit the propagation of RFID waves in sensitive areas. Based on the original gasket provided by the client, Isocover manufactures a custom replica in a shielded version, maintaining the same shape, flexibility, and mechanical properties as the original part. Its structure, made of conductive foam or flexible PVC coated with a Ni/Cu/Ni metallized fabric, absorbs and attenuates electromagnetic fields in gaps, junctions, and confined zones where films or coatings alone are not sufficient.
