<p>Method for the manufacture of a heat insulating foamed plastic material by foaming of a plastic material or plastic precursor material by means of a blowing agent where a mixture of krypton and xenon is at least partially used as a blowing agent. When using a mixture of krypton and xenon as the blowing agent, the ecological damages, particularly to the ozone layer, caused by the conventional CFC gases are avoided while a good heat insulating capacity is obtained at the same time.</p> |
