Designed for high-performance interference suppression, grid weave fabric over foam gaskets provide a reliable electrical path while acting as a soft mechanical cushion. By wrapping a highly conductive ripstop fabric around a resilient foam core, this gasket ensures continuous contact between mating surfaces, such as a PCB and a metal chassis, even when gaps vary in size.

The EMI shielding gasket’s reinforced grid texture is engineered to withstand physical wear and friction, maintaining its shielding integrity over thousands of compression cycles. With excellent conformability and low closure force, it effectively seals gaps against EMI/RFI radiation without putting stress on delicate components.
Key Features of Grid Weave Fabric Over Foam EMI Gaskets
- Superior Shielding: The conductive fabric cladding ensures shielding effectiveness of over 90dB across a wide frequency range, effectively blocking EMI/RFI radiation.
- Reinforced Durability: The ripstop grid texture prevents the fabric from fraying or tearing during installation and use, offering a longer service life than plain weave options.
- Low Compression Force: The soft foam core allows the gasket to compress up to 50-70% with minimal force, reducing stress on the device housing or PCB components.
- Excellent Resilience: Features low compression set, meaning the gasket returns to its original height after compression, ensuring constant electrical contact over time.
- Easy Application: Supplied with a conductive pressure-sensitive adhesive (PSA) for quick peel-and-stick assembly.
Common Applications of Grid Weave Fabric Over Foam EMI Gaskets
- I/O Backplane Shielding: Gaskets for USB, HDMI, and Ethernet ports.
- Housing Seals: Filling gaps between the metal chassis and plastic cover in smartphones, tablets, and laptops.
- Vibration Dampening: Acting as a conductive cushion to prevent rattle and ground internal components.
- Drones & Automotive: High-durability grounding pads in high-vibration environments.
