Types of EMI/RFI Shielding Silicones

Mil-DTL-83528 QPL Certified

SSP is a DLA listed manufacturer to Mil-DTL-83528 conductive elastomer products including Sheets stock, extrusions, o-rings, molded, and die cut gaskets.

emi shielding

Corrosion Resistant

Nickel plated aluminum filled silicones and flurorosilicones designed for corrosive environments with heavy salt spray including military ships and marine applications.

emi shielding

Low Shore A/Soft

Softer conductive elastomer allowing for lower enclosure force and better sealing capabilities as low 30 shore A.

emi gasket material selection

Fuel and Solvent Resistant

Fluorosilicone based conductive elastomers for fuel and solvent EMI gasket applications including jet fuels and de-icing fluids amongst other harsh fluids.

Low Outgassing

SSP has designed low outgassing conductive elastomers for space and high vacuum applications. Testing to ASTM595 via third-party labs available.

Most conductive

These silicones are extremely conductive elastomers where the lowest possible surface conductivity is required.

Flame Retardant

UL94 V0 vertical burn tested conductive elastomers where flame retardant specifications along with EMI shielding and environmental sealing is required.

SSP-5259 Nickel Aluminum Shielding Silicone


Conductive fabric reinforced shielding elastomer for maximum structural stability used in thin wall parts to prevent tearing.

EMI Connector Gaskets

Mil-DTL-83528 Connector gaskets, including EMI shielding for D-sub, USB, RF/coax, and power electrical connectors.

SSP502-65 supports thinner, smaller, and lighter-weight designs. This EMI RFI elastomer also offers performance levels that are comparable to shielding silicones with silver-coated particles. SSP502-65 is cost-effective and, unlike silver-filled silicones, isn’t subject to fluctuating silver prices.

Non-Silicone Based EMI Elastomer

SSP2514-75 is a nickel coated graphite filled conductive EPDM based shielding elastomer. It is used when looking for excellent ozone and UV resistance along with good compression set and solvent resistance.
