Abstract
A polycarbonate resin foamed molding having a density D of 0.6 g/cm3 or less and at least 30 (kg·cm/cm3)/(g/cm3) of a value E80/D obtained by dividing an amount of energy absorbed through 50% compression of the molding at 80° C. (E80 kg·cm/cm3) by the density of the molding. A shock absorber for a vehicle includes a core of the above molding, and a skin covering a surface of the core.
Claims4
A polycarbonate resin foamed molding obtained by molding polycarbonate resin expanded particles in a mold, said molding having a density of D g/cm3 and absorbing an energy of E80 kg·cm/cm3 when compressed to 50% at 80° C., wherein said density D and energy E80 meet with the following conditions:
- D≦0.6 E80/D≧30.
