Schlegel Electronic Materials, Inc. (SEM) introduces a new line of EMI foam, CF Conductive Foam. SEM CF Foam, a highly resilient Nickel-Copper polyurethane foam is sandwiched between SEM’s knitted and non-woven fabrics to form industry-leading die-cut gaskets. Conductive Foam material is ideal for applications that require conformity with excellent cavity-to-cavity EMI shielding, superior conductivity at low compression forces and better effectiveness at very high frequencies. EMI foam-based gaskets are precision die-cut with either conductive or non- conductive pressure-sensitive adhesive (PSA).
