ABSTRACT:
A foamed pad material for low-pressure compression molding which comprises a crosslinked rubbery olefinic soft resin foam and exhibits (a) a hysteresis loss of not greater than 40%, (b) a gel fraction of 20 to 98%, and (c) a density of 0.025 to 0.30 g/cm.sup.3. This foamed pad material is excellent in heat weldability with core forming materials and exhibits excellent heat resistance, strain resistance, moldability and restoring properties at the time of low-pressure compression molding at which compression and drawing are carried out at high temperatures. Moreover, the foamed pad material can allow the molded skin material to have cushioning properties with high flexibility and further to have improved feeling.
