Method for producing porous polytetrafluoroethylene film and porous polytetrafluoroethylene film |
| abstract |
Provided is a method for producing a porous polytetrafluoroethylene film excellent in chemical resistance and heat resistance, having a high porosity and excellent in dimensional stability. A stretching step of stretching the sheet-like molded body of a fluororesin mainly comprising polytetrafluoroethylene at a temperature lower than the melting point of the fluororesin in the machine direction and / or the transverse direction to form a porous fluororesin film; And an annealing step of keeping the porous fluororesin film in a shape-fixed state and storing and holding the fluoropolymer film at a temperature lower than the melting point of the fluororesin and a melting point of -30 占 폚 or more for 1 to 20 hours. A method for producing a fluoroethylene film. |
