Low Density Foam

While Burchard was experimenting with refrigerator insulation, he came up with a novel way of molding low-density foam.

那年伯查德正在做有关冷冻机隔热材料的实验，实验中他使用新的方法做出一种低密度的泡沫材料。

Carbon materials, including graphite, carbon fibre, carbon foam and expanded graphite possess the properties of high conductivity, low density and good chemical stability.

碳材料如石墨、碳纤维、碳泡沫和膨胀石墨，他们都具有高导热系数、低密度和良好的化学稳定性。

The tendency for replacement of CFC-11 and low density molded foam technologies is also discussed.

对CFC - 11替代、模塑泡沫低密度化等方面技术发展趋势加以讨论。
