1. Sound absorption and sound insulation: The 3D wave peak acoustic design effectively reduces noise. The threedimensional mesh porous material features interconnected gaps, which efficiently absorb volume, diminish noise, and decompose sound waves. 2. Good resilience: The absorption heatproof foam has a deformation rebound rate, ensuring ease of use and processing. It can be shaped into various forms to meet different needs, offering wear resistance and a soft texture. 3. Doublelayer composite material: The sound acoustic foam is made of polyester fiber and molded into a cocoonlike shape through hot pressing. Using a heat treatment method, density diversification is achieved, making it both a soundabsorbing material and a finishing material without volatiles. Composed of two polyester fibers with different melting points, it is odorless, nontoxic, and fireproof. 4. Versatile applications: The egg crate panel is suitable for home sound insulation, industrial noise reduction, cinemas, studios, cars, and more.
