100% Recycling Soundproofing Closed Cell Aluminum Foam Panel
What is AluminumFoam?
Aluminum foam is a new concept metalmaterial which is foamed in sponge shape after melting aluminum ingot with various chemical ingredients and has many bubble layers inner structure.
Porous material is much lighterthan original one, which is the characteristic of porous. And, it improves the ability of energy absorption and reduces the abilityof thermal and electrical conductivities than original metal materials. Inaddition, porous material has wide applications as well as excellent ability ofsound absorption and permeability of liquid, air, etc.
Aluminumfoam, a metal itself, can be applied to aerospace aviation required the thermostability over 200℃. It is a 100% recyclabl ecofriendly material and absolutely will not produceharmful substances no matter in the process of producing, using or abandoning.
Main properties of aluminum foam
Density is 0.2~0.4g/cm3 (Aluminium1/10,Iron1/30, and Wood 1/4)
Soundabsorption
Porous structure has a good soundabsorption.
Aluminum foam sound-absorbing materialcan be used in the inner decoration of buildings (walls, ceiling and floor),railway, highway, factories, mechanical equipment and any other fields.
Suitable for noisy place.
100%non-flammability and no toxic gas released when burning.
Non-combustibility TEST verified to be qualified. <KIMM; IMO A.799 (19)>
I grade Non-flammability TEST ofaluminum foam surface verified to be qualified. <KICT; KS F2271>
Energyabsorption
Porous structure can effectively absorbenergy.
Have a great effect on energyabsorption after a high impact.
Firstly acquired the national SB5class (Guard rail shock-absorber)
Electromagnetic wave shielding ability
Aluminum foam has a function ofabsorbing electromagnetic wave
Widely used in military (stealth materials),TV station, hospital and any other electromagnetic shielding places.
100% recyclable Aluminum foam is nonpoisonous, odorless andharmless, no toxic gas released when burning.
Aluminum foam can be produced by recycled aluminum andits scraps.
