SOUND ABSORBING MATERIAL AND SEALING MATERIAL
A sound absorbing material is obtained by foaming a rubber composition containing an ethylene-propylene-diene rubber. The content ratio of sulfur in the sound absorbing material calculated by a fluorescent X-ray measurement, based on mass, is 1000 ppm or less. The sound absorbing material has a 50 %...

| description | A sound absorbing material is obtained by foaming a rubber composition containing an ethylene-propylene-diene rubber. The content ratio of sulfur in the sound absorbing material calculated by a fluorescent X-ray measurement, based on mass, is 1000 ppm or less. The sound absorbing material has a 50 % compressive load value of 0.1 N/cm 2 or more and 10 N/cm 2 or less. The sound absorbing material has a 50 % permanent compression set of less than 50 %. |
