[Problem] To obtain good soundproofing properties without causing problems such as degradation of physical properties, increase in weight, deterioration in material handling properties, and whitening. [Solution] The rubber contains 5-45 parts by mass of uncrosslinked EPM and oil in at least the same amount (in parts by mass) as that of the EPM, per 100 parts by mass of crosslinked rubber polymer (excluding EPM), the rubber being foamed, and having a specific gravity of greater than 0.3 and no more than 0.8. A weather strip 1 and hose 2 are composed of the rubber. |
