EMI Shielding Materials and EMI Gasket Materials

SSP makes EMI shielding materials that provide alternatives, or offsets, to products from Parker Chomerics CHO-SEAL and Nolato J-Bar.

Our EMI gasket materials are made of electrically conductive silicones and are supplied as sheets, rolls, extrusions, and moldable compounds.

You can also choose EMI gaskets and EMI O-rings.

All of SSP’s EMI shielding materials are Made in the USA at our ISO 9001:2015 certified manufacturing facility in Ballston Spa, New York.

Types of EMI Shielding Materials

MIL-DTL-83528 QPL Certified EMI Gasket Materials

SSP makes EMI shielding materials that meet the lettered requirements of MIL-DTL-83528, a standard from the U.S. military. All of our M83528 shielding silicones are part of the Qualified Product List (QPL) from the Defense Logistics Agency (DLA). Choose Type A, B, C, D, and K materials for EMI gaskets and EMI O-rings.

Low Durometer/Soft EMI Gasket Materials

SSP makes softer, electrically conductive silicones in durometers as low as 30 Shore A. These EMI silicones allow for lower enclosure forces and better sealing capabilities. Products include offsets to discontinued EMI gasket materials from W.L. Gore.

Fuel & Solvent Resistant EMI Shielding Materials

EMI shielding materials that use fluorosilicone as the base elastomer provide fuel and solvent resistance. Applications include jet fuels, de-icing fluids, and other harsh chemicals. These electrically conductive silicones include a QPL listed MIL-DTL-83528 material.

Reinforced EMI Shielding Silicones

Conductive fabric reinforced shielding elastomer for maximum structural stability used in thin wall parts to prevent tearing. Learn more about these electrically conductive silicones.

ssp502-55LT | emi seal material

SSP’s most cost-effective EMI shielding materials, SSP502-65, supports thinner, smaller, and lighter-weight designs.  Unlike silver-filled silicones, this nickel-graphite filled EMI shielding material isn’t subject to fluctuating silver prices.
