热绝缘膨体聚四氟乙烯制品
摘要：
描述了热绝缘材料和制品。在一个实施方式中，热绝缘材料包括聚合物基质、气凝胶颗粒和膨体微球；其中，气凝胶颗粒的量为30重量％或更高，聚合物基质的量大于或等于20重量％，并且膨体微球的量为0.5重量％至15重量％，重量百分比是基于聚合物基质、气凝胶颗粒和膨体微球的总重量计；并且在大气条件下，热绝缘材料的热导率小于40mW/m K。
摘要（英）：

Thermally insulative materials and articles are described. In one embodiment, a thermally insulative material comprises a polymer matrix, aerogel particles and expanded microspheres, wherein the aerogel particles are present in an amount of 30% by weight or greater, the polymer matrix is present in an amount of 20% by weight or greater and the expanded microspheres are present in an amount of 0.5%to 15% by weight, the percentages being based on the total weight of the polymer matrix, the aerogel particles and the expanded microspheres, and wherein the thermal conductivity of the thermally insulative material is less than 40 mW/mK at atmospheric conditions.
