求翻译：当直接用PU制备绝缘导热膜时，由于PU粘度较大，不易成膜，且无法测试；单独用PVDF时，膜的柔软度不高膜比较脆，不适用服装；当两种材料以一定比例共混时，两种材料的性能得到综合，比较容易成膜，也能有很好的柔软度。是什么意思？

Is on duty when takes over the use of the PU preparation insulation heat conduction membrane, because the PU viscosity is big, not Yi Chengmo, also is unable to test; When alone uses PVDF, the membrane softness not high membrane quite is crisp, is not suitable the clothing; When two materials altoge
