绝热材料
摘要：
本发明的目的在于提供一种绝热性能和环境性能优异的树脂发泡体，其孔隙率(X)为80％以上，具有孔径为1μm以上1000μm以下的孔隙(L)和孔径为0.01μm以上且小于1μm的孔隙(S)，此外还提供长期保持优异的绝热性能、不易发生结露的无氯氟烃系绝热材料，其特征在于，孔隙率(X)为80％以上，具有孔径为1μm以上1000μm以下的孔隙(L)和孔径为0.01μm以上且小于1μm的孔隙(S)。
摘要（英）：

A resin foam is provided which has a porosity (X) of 80% or higher and has pores (L) with a pore diameter of 1-1,000 [mu]m and pores (S) with a pore diameter of 0.01-1 [mu]m, excluding 1 [mu]m. The resin foam is excellent in heat-insulating performance and environmental performance. Also provided is a chlorofluorocarbon-free heat-insulating material. This heat-insulating material retains excellent heat-insulating performance for long and is less apt to suffer dew condensation. The heat-insulating material is characterized by comprising a resin foam having a porosity (X) of 80% or higher and having pores (L) with a pore diameter of 1-1,000 [mu]m and pores (S) with a pore diameter of 0.01-1 [mu]m, excluding 1 [mu]m.
