Wave acoustic foam is made from sponge. It can come into direct contact with the human skin without producing any side effects. It is colorless, odorless, and does not release pollutants. It is the most environmentally friendly sound-absorbing material closest to nature. When used for internal partitions or wall sound insulation, it has better environmental protection and sound absorption effects than fiberglass, and is 100% recyclable. Its smoke density and toxicity are lower than national environmental standards. It is an environmentally friendly material widely used in building decoration in Europe, America, South Korea, and Japan. Soundproofing and noise reduction.
