Hollow Round Strip for EMI/RFI Shielding Extrusions


Hollow Round Strip solutions from Leader Tech include TechSIL round and hollow round EMI/RFI shielding conductive elastomer extrusions. These profiles are available in over thirty sizes to fit a wide range of applications.

To ensure proper performance, grooves are recommended in your device design. This helps prevent over-compression and improves the lifespan of the Hollow Round Strip gasket.

Bonding and Custom Options

Both round and hollow round Hollow Round Strip profiles can be bonded into O-rings using RTV cold bonding or hot vulcanized bonding methods.

For best results, bonded O-rings should have an inside diameter greater than 2 inches. However, if a smaller size is required, our engineering team can assist with custom solutions.

Performance and Design Benefits

The Hollow Round Strip profile offers a wider operating range and requires lower compression forces. As a result, it is ideal for applications that need flexibility and consistent sealing performance.

Please note that these profiles do not support pressure-sensitive adhesive, and tape options are not available. However, additional sizes can be provided upon request to meet specific application needs.

Hollow Round Strip

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.
