ISOLAMENTO CONTENDO MICROESFERAS |
摘要 |
<p>An insulated article having a first insulation region comprising a first polymeric material and first hollow ceramic microspheres and a second insulation region comprising a second polymeric material and second hollow ceramic microspheres. The first insulation region has a thermal conductivity that is no greater than the thermal conductivity of the first polymeric material and a volumetric heat capacity in a range of 60% to 90% of the volumetric heat capacity of the first polymeric material. The second insulation region has a thermal conductivity that is no greater than 90% of the thermal conductivity of the second polymeric material and a volumetric heat capacity that is less than 60% of the volumetric heat capacity of the second polymeric material. A method for making a composition for insulating an article is also described.</p> |
