Our factory independently foams and professionally produces sound-absorbing sponge, sound-absorbing sponge and sound-insulating sponge. It is made of polyurethane material and produced through an assembly line foaming process. It has excellent sound absorption, noise reduction and shock absorption effects. The pyramid-shaped material is filled with tiny voids inside, and the semi-open structure can absorb a large amount of the incident sound energy, attenuating the sound waves. It is a high-performance product for noise reduction, sound absorption and shock absorption materials. Its noise reduction capacity and fire resistance performance can be applied in industries and places such as vehicle construction, factory building noise reduction and building noise reduction and insulation projects, product packaging and padding, generator set noise reduction, air conditioning, acoustic laboratories, music recording studios, audio equipment, test rooms, surveying rooms, KTV rooms, and star-rated hotels.
