2400 Series Metalized Fabric over Foam
Do your products require a high-attenuation shielding? Our nickel-plated, RoHS-complaint metalized fabric-over-polyurethane gaskets are just what you need. Tech Etch’s foam core gaskets are setting a new standard for EMI shielding. Bonding the substrate to the core ensures self-termination when cut and offers top-notch flexibility. Our product profiles have a compression set of less than 3%.
For easy installation, our stick-on mounting features double-sided, pressure-sensitive tape. Just apply on a clean surface and allow a full 24 hours for curing.

2600 Series Metalized Fabric over Foam
In addition to our 2400 series, we also offer a 2600 version. Our custom shielding gaskets use metalized fabric wrapped around a polyurethane foam core where low-cost steel rule dies are used for cutting the fabric . The fabric is bonded to the core, to assure self-termination when needed.
These gaskets can be custom-cut to your specific shape and size. Be sure to consider the following when creating a design for your gaskets:
- The minimum distance between any cutout to the edge should be equal to the thickness of the material.
- The minimum hole diameters should also be equal to the material thickness.
- The softness of the material will influence the dimensional tolerance.
D-Connector Metalized Fabric over Foam
If you don’t need a custom gasket, Tech-Etch can provide you with a standard D-connector gasket. These gaskets shield most 9-pin through 50-pin connectors. We offer 5 standard sizes and 4 different thicknesses for each size. Our gaskets are made of metal or conductive elastomers.
Example: Part number 2640-1111-3015-040 is a 15-pin D Connector Gasket.
