The closed-cell aluminum foam is a metal material that its inner holes are sealed and closed to each other. Similar to the open-cell aluminum foam product, the closed-cell aluminum foam is very effective in sound absorption, electromagnetic shielding and structural damping. It also absorbs impact energy, regardless of impact direction. The closed-cell aluminum foam is more stable than organic materials such as wood or plastics, so it can used in many fields, such as heat shield, storage medium, fuel cell and heat exchanger. High strength, light weight (floating in water)， high energy absorption and fireproffing characteristic make the closed-cell aluminum foam popular in building industry, like outwall decoration, celling decoration, stair-step and so on.The material of our closed-cell aluminum foam is completely recyclable and therefore does not cause any damage to our environment.
