1. Hi-tech new foamed aluminum board, good sound-absorbing performance, stable acoustic performance, no pollution, light mass, attractive appearance, fire retardancy, water resistance, good physical performance and easy processing. Sound-absorbing bodies, mufflers, sound insulation structures, sound barriers, muffling rooms and sound insulation covers in various forms made of the board can directly face noise sources without any protective panels or other sound-absorbing filler. 

2. Excellent acoustic performance: Average sound-absorbing coefficient≥ 0.*0 (*******0Hz frequency range, determined by Acoustics Institute of Tongji University); Excellent acoustic performance that the sound-absorbing performance has no change after the board is sprayed with water and dust. 

3. The foamed aluminum board is molded by die-casting aluminum alloy. Once damaged, the board can be wholly recycled, which is currently the only green new hi-tech product causing no secondary pollution to environment. 

4. The foamed aluminum board is currently the cutting-edge and replacement product for non-fibrous material in the world, which cannot become flying dust to cause secondary pollution to atmospheric environment after being aged by sunshine, rain, high temperature and other environments like glass fiber, mineral wool, rock wool and other similar materials. 

5. The product has the corresponding fireproof noninflammability, weather resistance, corrosion resistance and aging resistance of aluminum and can withstand wind, rain and sunshine, belonging to Grade-A non-combustible products. 

6. The product can be coated with coatings in different colors, having attractive appearance; The coatings undergoing repeated diluted spraying, drying and other processes do no fade even under the condition of being exposed to wind and sun. 

7. The product has good electromagnetic shielding performance. 

8. The foamed aluminum sound-absorbing board can be sawn, bonded at random, riveted and inserted, convenient to install. 

9. The foamed aluminum board can be made into sound-absorbing bodies in various forms, or can be combined to be sound-absorbing or sound-insulating bodies in various forms. 

*0. The surface of the product is easy to clean and convenient to maintain.
