Substrate for liquid filter |
| abstract |
The present disclosure is a substrate for a liquid filter comprising a polyolefin microporous membrane, wherein the average flow pore diameter is 1 nm or more and 50 nm or less in the pore diameter distribution of the polyolefin microporous membrane measured by a half-dry method by gas/liquid substitution. , The content of calcium in the polyolefin microporous membrane is 2000 ppb or less, and the tensile elongation in the longitudinal direction (MD) and the tensile elongation in the width direction (TD) orthogonal to the longitudinal direction (TD) of the polyolefin microporous membrane. A substrate for a liquid filter having a ratio of (MD/TD tensile elongation ratio) of 0.47 or more and less than 0.96, or more than 1.25 and 7 or less is provided. |
