Our factory specializes in foaming silencer sponge, sound-absorbing sponge and sound-proof sponge. It is made of polyurethane material and foamed by assembly line. It has good sound absorption, noise reduction and shock absorption effect. The interior of the Reed-shaped material is filled with small gaps. The semi-open hole structure can absorb a large amount of injected sound energy and play a role in attenuation of sound waves, it is a high-performance product of noise reduction and damping materials. The sound attenuation ability and fire prevention ability are applied to: vehicle construction, factory building noise reduction and building noise insulation engineering, product packaging and padding, generator set noise reduction, air conditioning, Acoustic Laboratory, music studio, audio, audition room, mapping room, KTV room, star hotel and other industries and places.
