Bekipor® fiber media for sound attenuation

Bekipor® fiber media for sound attenuation
Bekipor® is a family of nonwoven 3D  media that consists of very fine steel metal fibers. Due to its unique structure, this random filler matrix media is excellent at absorbing sounds and vibrations. Depending on the desired sound absorption Bekaert offers a wide range of media with different pore sizes and flow resistivity.

Safe and reliable properties

Thanks to its non-flammable and corrosion resistant properties, Bekipor® can be used to reduce noise in applications that are exposed to high temperatures and other extreme conditions. Featuring low thermal expansion enables Bekipor® to cope easily with fast changing temperatures. This makes it a particular useful medium for airplane APU’s, air-conditioning systems or engines close to the fuselage of the aircraft.

Easy to process

The fiber-based structure can be shaped and molded in any size or panel type to fit the work environment without losing its effectiveness.
