폴리올레핀 미다공막의 120℃에서의 TD 열수축률이 8％ 이하이고, 그리고 폴리올레핀 미다공막의 130℃에서의 TD 열수축률이, 120℃에서의 열수축률의 3배 이상 5배 이하이고, 또한 120℃에서의 열수축률보다 12％ 이상 크다. This polyolefin microporous membrane has a TD thermal shrinkage at 120°C of 8% or less, and the TD thermal shrinkage at 130°C thereof is 3 to 5 times greater than the TD thermal shrinkage at 120°C and at least 12% greater than the TD thermal shrinkage at 120°C.
