As the melamine foam with a flexible, light weight and excellent acoustic properties, melamine foam is also used in the automobile industry as filler.

Melamine foam is a fully three-dimensional grid structure of the whole system, the grid aspect ration is L/D between about 10 to 20, its very high open porosity characteristics (density 20kg/M3 the melamine foam’s opening rate of 99% or more) can easily and effectively make sound waves into the foam and into the deep shock of the grid can be consumed and absorbed, and effectively eliminate the reflected wave.
