    • 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.
    • 一种绝缘制品,其具有包括第一聚合材料和第一中空陶瓷微球的第一绝缘区域和包含第二聚合物材料和第二中空陶瓷微球体的第二绝缘区域。 第一绝缘区域具有不大于第一聚合物材料的热导率的热导率和在第一聚合物材料的体积热容量的60%至90%的范围内的体积热容量。 第二绝缘区域的热导率不大于第二聚合物材料的热导率的90%,并且体积热容量小于第二聚合物材料的体积热容量的60%。 还描述了制造用于制品绝缘的组合物的方法。
