Conductive Foam

Schlegel Electronic Materials (SEM) introduces 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.

CF 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. CF foam-based gaskets are precision die-cut with either conductive or non- conductive pressure-sensitive adhesive (PSA).

Schlegel’s manufacturing and metal plating processes enhance the material integrity of the SEM Conductive Foam and ensure excellent galvanic compatibility even for large surface applications like I/O gaskets. The through-conductivity achieved with Schlegel CF increases the shielding effectiveness at high frequencies by shortening the return current path between the anges.
