Porous polytetrafluoroethylene resin film, porous polytetrafluoroethylene resin film composite, and separation membrane element |
| abstract |
A fluororesin mainly composed of polytetrafluoroethylene is formed on each of a plurality of kinds of polytetrafluoroethylene different in the heat of fusion and then sintered by heating at a temperature equal to or higher than the melting point to prepare a plurality of kinds of non- , A plurality of kinds of the non-porous resin films are stacked in the order of magnitude of the heat of fusion of the polytetrafluoroethylene used for the fabrication, and then the porous resin films are prepared by stretching and have an average flow pore size of 50 nm or less A porous resin film made of polytetrafluoroethylene and having a fine and uniform diameter through-hole and having excellent filtration efficiency even when used as a filter and having less clogging, a method for producing the same, And the composite is used as a filtration membrane. |
