Method Of Manufacture Of Polytetrafluoroethylene Stretched Film, And Polytetrafluoroethylene Stretched Film |
摘要 |
A method of manufacturing a PTFE stretched film that has higher tensile strength at its breaking point. In the method, a resin composition is obtained by mixing an emulsion of PTFE (A) with a number average molecular weight of 5×106 or more and an emulsion of PTFE (B) with a number average molecular weight of 1×106 to 4×106 so that the solid content ratio (A/B) of the PTFE (A) and the PTFE (B) is 99/1 to 10/90. The mixed emulsion is subjected to compression molding in a melted state under a reduced-pressure atmosphere to obtain a film.
