Schlegel Electronic Materials
Schlegel Electronic Materials, Inc. (SEM) invented highly conductive fabric over foam shielding gaskets in 1987, marking a major breakthrough for the electromagnetic interference shielding of electronic enclosures and has become the pre-eminent manufacturer of electromagnetic interference (EMI) shielding products.
Schlegel’s high-performance products include innovative Fabric Over Foam Gaskets, I/O backplane shielding gaskets, Conductive Elastomers, RF Absorber Materials, and other enclosure gaskets and board-level shielding products that enable the computer, telecommunications, military, medical, and electronics industries to meet global requirements for electromagnetic compatibility.
From concept to production, SEM’s complete portfolio of shielding products combines highly conductive materials with flexible foams and coatings to provide the latest EMI containment solutions. The company’s world-renowned EMI shielding gaskets are available in hundreds of profiles and unique designs, with attachment options including mechanical self-attaching, clips, rivets, and a variety of pressure-sensitive adhesives. Sometimes, a standard product off the shelf, or one with slight modifications, will suffice. But when you have unique, advanced, or complex product requirements, we have extensive custom capabilities.
We design and manufacture custom:
– Extruded components in many shapes and sizes,
– Die-cutting, and
– Profiles, or lengths.
As electronic components require higher watt densities, SEM’s line of high-performance TIMs can help design engineers address their thermal management challenges.
The OpTIM® thermal interface materials by Schlegel offer a wide range of thermal performance and physical properties and can resolve even the most challenging thermal problems. Our TIMs are widely used in demanding applications, including advanced microprocessors, high-speed memory modules, micro heat pipe assemblies, and LED lighting.
Our experienced team can support your design and increase your application’s long-term performance. We make it easy to get lower-cost, specialized, and complex custom molds for custom profiles built for the long haul.
Schlegel’s global footprint offers unparalleled support and service.
