Product Description
Fabric-over-Foam (FOF) Gaskets are advanced EMI shielding components made by wrapping conductive fabric or metal foil over a soft foam core. They combine excellent shielding effectiveness with mechanical flexibility and environmental sealing, making them ideal for use in electronic enclosures, seams, and access panels.
These gaskets address key challenges such as EMI leakage, irregular surface contact, and mechanical misalignment. Their compressible core ensures consistent shielding even under low closure force, while also compensating for uneven surfaces and gaps in device assemblies.
Compared to traditional EMI gaskets, our FOF gaskets offer superior elasticity, longer compression life, and custom profile options. Their enhanced conformability and durable construction make them a top choice for reliable and cost-effective EMI management.
