Design for Noise Reduction of the Interior of Building Using Microcellular Foamed Plastics

Autor: Hak Bin Kim, Earl Han, Sung Woon Cha

Publikováno v: Applied Mechanics and Materials. :936-939

The microcellular foamed plastics (MCPs) have high material strength, a relatively small cell size, and a high cell density in comparison with conventional foamed plastics. In particular, the small size of cell in MCPs makes many applications possibl
