Finding the Right Conductive Elastomer EMI Gasket For You

• Availability
• Design Flexibility
• Cost Effectiveness
• Proven Performance

Four of the reasons why CHO-SEAL^® conductive elastomer electromagnetic interference (EMI) gaskets are the right EMI shielding solution. Once used mainly to shield critical defense and aerospace electronic systems, Parker Chomerics conductive elastomers have become the progressive choice for designers of consumer, telecommunications, industrial equipment, automotive, medical devices and much more.

Conductive elastomers are reliable over the life of the equipment, and the same gasket is both an EMI shield and an environmental seal. Elastomer gaskets resist compression set, accommodate low closure force, and help control airflow. They’re available in corrosion-resistant and flameresistant grades. Their aesthetic advantages are obvious: almost any elastomer profile can be extruded or custom molded with modest tooling costs and short lead times for either prototypes or large orders.

Parker Chomerics offers hundreds of standard molded and extruded products, but we can can also take a customer-supplied design and deliver finished parts. Molded products provide moisture and pressure sealing and EMI/EMP shielding when compressed properly in seals, flanges, bulkheads, and other assemblies. Extrusions provide similar benefits and are also readily lathe-cut into washers, spliced, bonded, kiss-cut, or die-cut to reduce installation labor and to conserve material, resulting in a cost-effective alternative to other methods of EMI shielding and environmental sealing.
