What is a Rectangle D Cross Section conductive gasket?

A Rectangle D Cross Section conductive gasket is a molded conductive elastomer sealing solution designed for EMI/RFI shielding and environmental protection in rectangular connector and electronic enclosure applications.

What applications use Rectangle D Cross Section conductive gaskets?

Rectangle D Cross Section conductive gaskets are commonly used in aerospace electronics, military systems, telecommunications equipment, RF devices, medical electronics, and industrial electronic enclosures.

What are the benefits of D profile conductive gaskets?

D profile conductive gaskets provide reliable EMI shielding, strong environmental sealing, flexible installation options, corrosion resistance, and long-term conductive performance.

What conductive elastomer materials are available?

Available conductive elastomer materials include silicone and fluorosilicone compounds with conductive fillers such as silver/copper, silver/aluminum, silver/nickel, silver/glass, and nickel-coated graphite.

Can Rectangle D Cross Section gaskets be used without a groove?

Yes. TechSIL Rectangle D Cross Section conductive gaskets can be installed with or without a groove depending on the application and sealing requirements.

Are custom Rectangle D Cross Section gasket sizes available?

Yes. Leader Tech offers custom sizes, conductive compounds, and molded gasket configurations for specialized EMI shielding and sealing applications.

Total Mass Loss (TML): In general, the material is considered acceptable if the total mass loss (TML) is less than 1% and the volatile condensable mass (VCM) is less than
0.1% of the initial sample mass.
Collected Volatile Condensable Materials (CVCM): If the CVCM exceeds 0.1%, the material fails.
Water Vapor Regained (WVR): If the difference between the TML and the WVR does not exceed 1.0% (and the CVCM does not exceed 0.10%), the material passes the test.
