Porous polytetrafluoroethylene membrane and waterproof air-permeable member |
| abstract |
Provided is a porous polytetrafluoroethylene (PTFE) membrane that satisfies the following expressions: 0.2≦F≦4.0; 0.2≦R≦1.0; and R≧−0.1F+0.5, for the Frazier number F [cm 3 /sec/cm 2 ] and the water entry pressure R [MPa]. This porous PTFE membrane may be a single-layer membrane. This porous PTFE membrane has the properties suitable for use as a waterproof air-permeable membrane, and achieves a good balance between high water resistance and high air permeability. |
