Laird Fabric-over-Foam (FOF) EMI gaskets provide a wide range of excellent eletromagnetic interference shielding performance and offer excellent assembly tolerance absorbing for customers where EMI issues occur. They are composed of electrically-conductive fabric wrapped around a soft foam core, and supplied with a non-conductive or conductive pressure sensitive adhesive (PSA) as well as an extended release liner on the adhesive. They can be created with cross-section profiles such as rectangle, D, C, P, T, knife, bell shapes, and others, and can be further customized to an application by die-cutting, hole punching, notching, etc.
Features and Benefits
Shielding effectiveness of >100 dB across a wide spectrum of frequencies.
Extremely low compression forces allow for use of lighter materials.
Low Surface Resistivity as low as 0.07 ohms/square dependent on the fabric. Fabric-Over-Foam gaskets provide improved conductivity.
A wide range of flame retardant gaskets is available (UL recognized per UL94 V0 or UL94 HB). More information is available at ul.com.
Abrasion-resistant metallized fabrics show virtually no degradation in shielding performance.
