<p>A MICROPOROUS SOUNDPROFFING MATERIAL CONSTITUTED OF AN EXPANDED MATERIAL FORMED THROUGH THE STEP OF IMPREGNATING A THERMOPLASTIC ELASTOMER WITH AN INERT GAS AT A HIGH PRESSURE AND THEN DECOMPRESSING THE IMPREGNATED ELASTOMER. THE SOUNDPROOFING MATERIAL HAS A HIGH CHARACTERISTIC IMPENDANCE, IS CLEAN AND LIGHTWEIGHT, AND HAS EXCELLENT FLEXIBILITY. THIS MICROPOROUS SOUNDPROOFING MATERIAL INCLUDES: A MICROPOROUS SOUNDPROOFING MATERIAL WHICH IS CONSTITUTED OF AN EXPANDED MATERIAL FORMED THROUGH THE STEP OF IMPREGNATING AN UNEXPANDED MOLDING COMPRISING A THERMOPLASTIC ELASTOMER WITH AN INERT GAS AT A HIGH PRESSURE AND THEN DECOMPRISING THE IMPREGNATED MOLDING; AND A MICROPOROUS SOUNDPROOFING MATERIAL WHICH IS CONSTITUTED OF AN EXPANDED MATERIAL FORMED BY IMPREGNATING A MOLTEN THEMOPLASTIC ELASTOMER WITH AN INNERT GAS AT A HIGH PRESSURE AND THEN SUBJECTING THE IMPREGNATED ELASTOMER TO MOLDING SIMULTANEOUSLY WITH DECOMPRESSION.</p> |
