<p>A polycarbonate resin foam having a density D of 0.6g/cm3 or less, and also having a value of E¿80?/D which is obtained by dividing an energy absorbance at 50 % compression at 80 °C, E80 kg.cm/cm?3¿, by the density of the foam, of 30 (kg.cm/cm?3)/(g/cm3¿) or more. A shock absorber for a vehicle comprises a core made of this resin foam and a skin covering the surface of the core.</p> |
