Abstract
A fluorine resin film to be provided includes a fluorine resin, and has a surface subjected to a modification treatment. The fluorine resin film has, at the surface, the following proportion of each of carbon, oxygen, and fluorine elements based on 100 atom % of a sum of the elements: 30 atom % or more and 70 atom % or less of carbon; 0.6 atom % or more and less than 13 atom % of oxygen; and 60 atom % or less of fluorine. This fluorine resin film is a fluorine resin film having a surface subjected to a modification treatment, and is suitable for manufacturing a molded rubber body having a surface coated with the film.
Claims11
A fluorine resin film comprising an ethylene-tetrafluoroethylene copolymer as a fluorine resin, wherein
- the fluorine resin film has a surface subjected to a modification treatment, and has, at the surface, the following proportion of each of carbon, oxygen, and fluorine elements based on 100 atom % of a sum of the elements:
- 30 atom % or more and 70 atom % or less of carbon;
- 0.6 atom % or more and less than 13 atom % of oxygen;
- and
- 60 atom % or less of fluorine, with the proviso that
- a fluorine/carbon element ratio (F/C ratio) at the surface is 1.15 or more, and
- an oxygen/carbon element ratio (O/C ratio) at the surface is less than 0.08.
