是采用聚胺酯海绵材料。 Soundproof cotton is made of polyurethane sponge material. A special processing equipment to form a concave-convex wavy shape, foamed by a complicated process, a sound-absorbing, sound-absorbing, sound-insulating and shock-absorbing sponge material. The interior is filled with fine voids and semi-open-cell structures that can absorb a large amount of the incoming sound wave energy to attenuate the sound waves, reduce the interference and reverberation of the indoor reflected sound, and improve the purity of the sound.
The company's products are rare high-quality sound insulation materials, which are used for equipment sound insulation, KTV sound insulation, indoor noise reduction, machine room noise reduction, and bar noise reduction.

Sound insulation and muffler principle: It has a large number of internal and external pores and air bubbles. When sound waves enter it, it can cause air vibration in the gap. Due to the air's viscous resistance and the friction between air and the hole wall, a considerable part of the sound energy is converted into heat It is consumed. In addition, when the air is adiabatically compressed, heat exchange occurs between the air and the hole wall. Due to the heat conduction effect, a part of the sound energy is also converted into heat energy.
