Abstract
PURPOSE: To obtain a foam best suitable for such applications as fload and container, etc., by putting thermal plastic resin foaming particles into a mold, introducing steam into it, heating it under a particular condition to accelerate their foaming, and cooling it naturally and also by using cold water.
CONSTITUTION: A mold of double-wall construction, equipped with a steam chamber on its outside of a required configuration contour, is charged with thermal plastic resin foaming particles. Steam is immediately introduced into this mold from a sbeam chamber, and the inside steam pressure is maintained at 1.5W3 kg/cm2 (Gage Pressure) for 1W240 seconds, more preferably at 2W2.5 kg/cm2 for 30W180 seconds. And then, the steam supply is stopped, the mold is left alone for natural cooling and then cooled with cold water so that the foam in question can be obtained.
