Increase in sound absorption in foam insulating materials |
| abstract |
The present invention is directed to the use of expandable graphite having an initial temperature of at least 150 캜 to improve the degree of sound absorption in the expandable graphite-expanded sound-absorbing foam wherein the foam is a polyurethane foam. The sound absorbing material of the present invention comprises an integral or soft sound absorbing polyurethane foam which is at least an open cell in the core region and has a density of not less than 120 g / l and an initial temperature of not less than 150 ° C for 100 parts by weight of the isocyanate- Lt; RTI ID = 0.0 > 5% < / RTI > by weight of the expandable graphite. The sound absorbing material can be preferably used for an engine part of an automobile. The sound absorbing material is also very advantageously used in the interior of relatively complex parts and in the design-dependent cavity of the machine. |
