Conductive Foam for EMI Shielding

Schlegel Electronic Materials (SEM) introduces NEW 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).

100% RoHS Compliant

Schlegel Electronic Materials products are employed around the world. Therefore, we are committed to comply with the European Union Directive 2002/95/EC (RoHS). SEM products and materials have been tested by approved third party facilities and found to be in full compliance with the RoHS threshold limits.

The “New” Schlegel Electronic Materials
As the originator of the fabric-clad foam EMI shielding technology, Schlegel Electronic Materials is the industry’s most trusted name. SEM continues to set the standard for quality and innovation, designing advanced solutions for a wide range of applications. And our worldwide locations ensure that you get what you need - when and where you need it. From concept to production, the SEM complete portfolio of shielding products combines highly conductive materials with flexible foams and coatings to provide the latest electronic materials containment solutions.

Schlegel Electronic Materials objective is to ensure that its customers have a competitive edge by offering the highest quality and most cost-effective products conveyed with the highest level of customer service.
