Secondary Insulation — EMI & Mechanical Protection
Lightweight EMI Shielding and Protection That Flexes With Your Cable.
Gore Protective Braids combine EMI shielding effectiveness with the mechanical protection of an outer braid, while preserving the flexibility and routeability that modern cable assemblies demand. Built with ePTFE as a key structural element, they outperform conventional metallic braids in corrosion resistance, weight, and flexibility retention across the full operating life.

Gore ePTFE braids provide lightweight EMI shielding and mechanical protection while maintaining the cable assembly's flexibility and routing capability.
Why Choose Gore Protective Braids?
Effective EMI Shielding
Gore Protective Braids achieve high shielding effectiveness across a broad frequency range, protecting sensitive signal cables from external EMI and preventing radiated emissions from power cables from interfering with adjacent electronics. This is critical in military platforms, medical devices, and semiconductor test equipment where EMC compliance is mandatory.
Lighter Than Conventional Metallic Braids
Incorporating ePTFE in the braid construction reduces the overall weight compared to all-metallic braids of equivalent coverage. In aerospace and medical applications where every gram is accounted for, this weight advantage compounds across large cable harnesses.
Flexibility Retained Through Service Life
Conventional metallic braids can stiffen and fatigue with repeated flexing. Gore's ePTFE-based braid construction maintains the cable assembly's flexibility throughout its rated service life, allowing for dynamic routing and repeated maintenance handling without braid cracking or coverage degradation.

Frequently Asked Questions
What shielding effectiveness levels do Gore Protective Braids achieve?
Shielding effectiveness depends on braid coverage percentage, frequency, and specific braid construction. Contact RSTECH Electronics for shielding effectiveness data relevant to your frequency range and application.
Can these braids be grounded at both ends for better shielding?
Yes. Like conventional metallic braids, Gore Protective Braids can be terminated and grounded at both ends (or single-ended) depending on the shielding strategy for the application. Termination methods are compatible with standard aerospace and industrial connector backshells.
How do Gore Protective Braids perform in high-humidity environments?
ePTFE is inherently hydrophobic and does not absorb moisture. Gore Protective Braids maintain their mechanical and shielding properties in high-humidity environments, unlike some conventional braid materials that can corrode or degrade when wet.
Are Gore Protective Braids suitable for medical device applications?
Yes. The chemical inertness and cleanability of ePTFE make Gore Protective Braids suitable for medical device cable assemblies. Contact RSTECH Electronics to discuss biocompatibility documentation if required for your application.
