Method for producing modified molded article of fluororesin
A method for producing a modified molded article which includes molding a fluororesin to provide a molded article and irradiating the molded article with radiation at an irradiation dose of lower than 100 kGy at 50° C. to 200° C. to provide a modified molded article.
1. A method for producing a modified molded article comprising:
molding a fluororesin to provide a molded article; and
irradiating the molded article with radiation at an irradiation dose of lower than 100 kGy at an irradiation temperature of 50° C. to 200° C. and that is also lower than the melting point of the fluororesin to provide a modified molded article.
2. The production method according to claim 1 ,
wherein the molded article has a thickness of 0.01 to 3.0 mm.
3. The production method according to claim 1 ,
wherein the molded article is a tube, a film, or a bottle.
4. The production method according to claim 1 ,
wherein the modified molded article has a specific gravity of 2.14 to 2.30.
5. The production method according to claim 1 ,
wherein the fluororesin is a melt-fabricable fluororesin.
6. The production method according to claim 1 ,
wherein the fluororesin is a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer.
7. The production method according to claim 1 ,
wherein the fluororesin contains 0 to 500 functional groups per 10 6 carbon atoms in the main chain.
8. A modified molded article which is obtainable by the production method according to claim 1 .
