EMI/RFI Shielding

Metafil Mat® is the ultimate material to provide effective shielding from electromagnetic interference. Our Metafil Mat is used in radar blocking equipment for the military and in shielding for satellite antennae.

Metafil consists of aluminum coated glass fibers thermally bonded into a nonwoven mat of uniform density. The fibers are oriented to provide superior electrical and shielding performance. The structure of the material allows for conformability to irregular surfaces and compatibility with other base substrates or resin systems.

This material is manufactured in a well-controlled environment to assure product uniformity and performance. The structure of the material allows for conformability to irregular surfaces and compatibility with other base substrates or resin systems.
