Anti electromagnetic wave aluminum foam material with through hole foam aluminum (10010010mm)

1, high-tech, new foam aluminum plate, sound absorption performance is good, acoustic performance is stable, no pollution, light weight, beautiful, fire prevention, no fear of water, good physical properties, easy to process, use it to make various forms of sound absorbing body, muffler, sound insulation structure, noise barrier, silencer room, sound insulation cover, etc., can directly face the noise source, do not need any protective panels and other sound absorption fillers. 2. It has excellent acoustic performance: average sound absorption coefficient ≥ 0.60 (125-4000hz frequency range, measured by Institute of acoustics, Tongji University); it also has excellent acoustic performance that the sound absorption performance does not change after spraying water and ash. 3, aluminum foam is made of aluminum alloy by die casting. After being damaged, it can be recycled. It is a green and environment-friendly high-tech product that will not cause two pollution to the environment. 4, the foam aluminum plate is the world's leading and replacement products without fibrous materials. It will not be aged like dust, mineral wool, rock wool and so on. It will become dust dispersed and cause two pollution to the atmospheric environment. 5, with the corresponding metal aluminum fire non flammability, weatherability, corrosion resistance, aging resistance, withstand wind, rain, sun, is a class of non combustible products. 6. The coating can be applied with different colors, which is beautiful. The coating will not fade even under the condition of wind and sunlight after many times of thin spray, drying and other processes. 7. It has good electromagnetic shielding performance. 8. Foam aluminum sound absorbing board can be sawn, can be bonded, riveted and inserted, and is easy to install. 9, aluminum foam can be made into various forms of sound absorbing body, and can be combined into various forms of sound absorption and sound insulation.
