Acoustic insulation material

Byspecial production process,sound absorbingsheet has thespecial concave-convex body and honeycomb curved surface structure. The honeycomb-shaped and hole-opened curved surface of the material, can cause the sound wave repeated reflection weaken and reduce the noise transmission. The interior closed-cell structure can be effective forsound-insulated and heat-prevented. Many kinds of functions such as heat prevented, noise reduction and sound-insulated.
