An RF gasket combines environmental sealing and insulation with shielding against radio frequency interference (RFI). RF gaskets are used in applications where radio frequency (RF) signals are present, such as communication devices, military equipment, medical devices, and automotive electronics.
Specialty Silicone Products (SSP) makes EMI/RFI shielding silicones and can fabricate mold or cut the RFI gasket that you need. We made our materials at our Ballston Spa, New York (USA) manufacturing and have an in-house toolroom and laboratory. Plus, we sell RF gasket materials in low minimum order quantities. Â

Electrically Conductive Silicones and Fluorosilicones
An RFI gasket uses silicone or fluorosilicones as the base elastomer and is filled with metal, bimetallic, or metal coated particles that provide electrically conductivity. Examples include silver-aluminum, silver-copper, and nickel-graphite. Without these filler materials, silicones and fluorosilicones are electrically resistive instead.
Environmental Sealing and InsulationÂ
The primary function of an RF gasket is to seal gaps or seams in enclosures, cases, or housings. This prevents the ingress of water and keeps electromagnetic waves from entering or existing. Silicone elastomers also resist a wide range of temperatures and exhibit excellent thermal stability.
RFI Shielding Materials
RFI shielding materials provide protection against radio frequency interference (RFI), a form of EMI in the radio frequency (RF) portion of the electromagnetic spectrum.Â

SSP offers a certificate of analysis (COA) with each batch and publishes technical data sheets (TDS), EMI shielding reports, and other information on our website. Â
RF Gasket Compression
An RF gasket is designed to be compressed when the enclosure is closed, ensuring a tight seal that maintains shielding effectiveness over time. The RFI silicones that SSP offers are available in low durometers for applications where low compressive forces are present. Many of our RF gasket materials meet MIL-DTL-83528 requirements.
