According to melamine foams attractive properties, it has been widely applied in lots of industry segment:

Aerospace
The advantages of the low density and sound absorption capacity of Melamine foam also permit system applications in the aerospace industry. Thus foil-covered acoustic members made from Melamine foam are used for the cladding on the payload areas of launcher rockets.
These reduce acoustic pressures and in this way contribute to the protection of highly sensitive goods in transit, e.g. satellites.
