| titleOfInvention | Polyolefin microporous membrane for filtration filter and filtration device |
| abstract | 【Task】 Provided is a polyolefin microporous membrane for a liquid filtration filter, which has excellent collection performance for foreign substances of several nm or less and has excellent liquid permeability. SOLUTION: A microporous polyolefin membrane for a filtration filter having at least a first layer and a second layer and satisfying the following requirements (I) to (III). (I) The average flow rate hole diameter is 5 nm or more and 25 nm or less. (II) In the pore diameter distribution curve obtained from the pressure change of the air flow rate in the dry state and the wet state, among the pores detectable in the range of 0 kPa to 3000 kPa, the pore diameter showing the maximum peak of the pore diameter distribution is Dp (nm). ), The total value of the pore diameter distribution of the pores of 0.9 Dp to 1.1 Dp is 85% or more of the entire pores. (III) The porosity is 49% or more. [Selection diagram] None |
