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.

Thermoplastic Glass Reinforcement

PolyPreg® is the latest innovation in thermoplastic composite material from BGF Industries. PolyPreg® is a woven co-mingled Glass/Polypropylene fabric that can be directly consolidated, with the addition of heat and minimal pressure, into a high strength composite part. PolyPreg® has high glass content, high impact properties, unlimited shelf life, no emissions, is recyclable and easy to process. Parts made from PolyPreg® can be used in many applications—Automotive, Building & Construction, Marine, Sports & Leisure, and Transportation.

PolyPreg® fiber ratios can be customized. It is UV stable, soft, conformable to complex shapes, and is available in 750 GSM and 1500 GSM, in natural or black colors.
