SELBST UNTERDRUCK ERZEUGENDES VAKUUMPANEEL

摘要

The present invention provides an insulation panel comprising an air-impermeable container and disposed therein a gas and an adsorbent material that has a surface area of at least about 200 m2/g and that adsorbs more of the gas at a temperature below about 0 DEG C. than at 22 DEG C., wherein the pressure in the container at -34 DEG C. is not more than about 80% of the pressure in the container at 22 DEG C. The present invention also provides a method of insulating a surface from environmental thermal effects comprising placing the insulation panel of the present invention over the surface to be insulated.
