Abstract
Official abstract text for this publication.
The present invention aims to provide a fluororesin composition for a molded product that is excellent in tensile strength and flex resistance. The present invention relates to a fluororesin composition that contains a fluororesin and a fluorinated nanodiamond. The amount of the fluorinated nanodiamond is 0.001 to 5% by mass based on the fluororesin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fluororesin composition consisting of: a crystalline fluororesin; and a fluorinated nanodiamond, wherein the fluorinated nanodiamond is present in an amount of 0.01 to 5% by mass based on the fluororesin, wherein the fluororesin composition is obtained by kneading the fluororesin and the fluorinated nanodiamond at a temperature higher than a melting point of the fluororesin, and wherein the fluororesin is at least one selected from the group consisting of tetrafluoroethylene (TFE)/perfluoro(alkyl vinyl ether) (PAVE) copolymer, TFE/hexafluoropropylene (HFP) copolymer, TFE/ethylene (Et) copolymer, TFE/HFP/Et copolymer, TFE/HFP/vinylidene fluoride (VdF) copolymer, TFE/PAVE/chlorotrifluoroethylene (CTFE) copolymer, CTFE/Et copolymer, polychlorotrifluoroethylene, polyvinylidene fluoride and polyvinyl fluoride. 2. A molded product comprising the fluororesin composition according to claim 1 . 3. The molded product according to claim 2 , wherein the molded product has a recrystallized average spherulite size of 15 μm or smaller. 4. The molded product according to claim 2 , wherein the molded product has a recrystallized average spherulite size of 6 μm or smaller. 5. The molded product according to claim 2 , wherein the molded product has a recrystallized average spherulite size of 1 μm or smaller.
