Acoustic barriers--aluminum foam composite  with aluminum sheet. For the production of foamed aluminum, AL powder is mixed with a product releasing gas at higher temperature and then compacted, this foaming agent is placed into a mold form and heated up until the agent starts to foam. Immediately thereafter the mold is taken out of the furnace and cooled off, so the aluminum foam part is frozen in shape. The outcome of this process is a closed cell aluminum foam showing a thin casting skin on the surface. soundproof material. acoustic barrier

Property

Heat insulation and resistance

Non-inflammable

Absorption of high impact energies

Regardless of the impact direction

Highly efficient in sound absorption

Electromagnetic shielding and vibration damping

High stiffness at very low density

Aluminum foam (Closed cell) to qualify for specific requirements within the automotive, aviation, railway and engine building industry. Aluminum foam is also qualifying for other high potential applications in the field of Architecture and Design, where electromagnetic shielding, structural damping, flame resistance and a decorative surface structure is required.
