Sound insulation foam is a kind of very mature technology and low cost solutions to reduce noise.It is common sponge after high pressure molding.

Sound insulation foam Was first applied in the recording studio, conference room, KTV and other places, as people increasingly demands of quiet and comfortable living environment, sound insulation sponge begin to enter the family, as metope subsidiary structure, which can satisfy the need of you to create a tranquil environment, but also has certain ventilation.
