SOUND INSULATING MATERIAL AND SEALING MATERIAL |
| 摘要 |
This sound insulating material can be obtained by means of foaming a rubber composition containing an ethylene-propylene-diene rubber. The sulfur atom content calculated by means of fluorescence x-ray measurement is no greater than 1000 ppm by mass. The 50% compression load value is 0.1-10 N/cm2 inclusive. The air permeability is no greater than 10 cm3/minute/cm2. |
