HEAT-INSULATING BODY

摘要

The invention concerns a heat-insulating body comprising: a) a porous pressed shaped part having an apparent density of 50 to 350 kg/m3, preferably 100 to 250 kg/m3, which is obtained by comminuting foamed plastics to form powder or flakes, binding the powder or flakes with a binder and simultaneously or subsequently shaping the part by pressing; and b) a foil enveloping the pressed shaped part. The foil enveloping the pressed shaped part is evacuated and then hermetically sealed.
