Filter using ultra high molecular weight polyethylene porous membrane as filtration medium |
| abstract |
(57) Abstract: An object of the present invention is to provide an inexpensive filter that can be used in the field of electronics and has substantially no eluted components and does not cause disposal problems. SOLUTION: The object of the present invention is to form an ultra-high molecular weight polyethylene having a molecular weight of 4 × 10 5 or more into a gel by forming a gel, stretching the film in at least one direction after removing the solvent, to have a thickness of 10 to 300 μm and a porosity of 30. Ultra-high molecular weight polyethylene in which a polyethylene porous membrane having an average pore diameter of 0.03 to 5.0 μm and a tensile strength of at least 10 MPa in at least one direction is fibrillated at the time of stretching to form a nonwoven fabric. This is achieved by a filter using a porous membrane as a filtration medium. |
