The present invention relates to particulate compositions having improved thermal conductivity values. An embodiment of the present invention is a particulate composition which under a 103421 Pa load, at 20 DEG C., and at a pressure (P) within the range of 133.322-13332.2 Pa, in Nitrogen, has: a packing density of less than or equal to 160 kg/m3, and a Thermal Conductivity (TC) at 133.322-1333.22 Pa of less than or equal to (0.260 lnP+4.53) milliWatt/meterK (mW/mxK) and a TC at 1333.22-13332.2 Pa of less than or equal to (0.824 lnP+0.47) mW/mxK. A preferred particulate composition is a gel composition. Also disclosed are insulation bodies comprising the particulate compositions. |
