1, high-tech, new type of Closed cell foamed sheet metal, sound-absorbing performance is good, acoustic performance is stable, no pollution, qualitative light, beautiful, fire prevention, not afraid of water, good physical properties, easy processing, use it to make all kinds of sound absorption, sound insulation, muffler structure, sound insulation, sound insulation, sound room cover, etc., can be directly in the face of noise source, do not need any protection panel and other sound-absorbing packing.
2. Excellent acoustic performance: average sound absorption coefficient ≥0.60 (125-4000Hz frequency range);At the same time, it has excellent acoustical performance that does not change the sound absorption performance after spraying water and ash.
3. Closed cell foamed sheet metal is made of aluminum alloy die-casting. After damage, it can be fully recycled and utilized.
4. Closed cell foamed sheet metal is the leading edge and replacement product of non-fibrous materials in the world at present. It will not become dust flying and cause secondary pollution to the atmospheric environment after aging like glass fiber, mineral wool, rock wool and other environments caused by sun, rain and high temperature.
5, with the corresponding metal aluminum fire non-combustible, weather resistance, corrosion resistance, aging resistance, can withstand wind, rain, sun, is A grade A non-combustible products.
6, can be coated with different colors of coating, beautiful, coating after several dilute spray, drying and other processes, so even in the conditions of the wind and sun, will not fade.
7, with good electromagnetic shielding performance.
8, Closed cell foamed sheet metal can be seen, can be arbitrarily bonded, riveted, inserted, easy installation.
9, Closed cell foamed sheet metal can be made into various forms of sound absorption body, but also can be combined into various forms of sound absorption, sound insulation body.
10. The surface is easy to clean and easy to maintain.
