Fluorocopolymer film and its application |
摘要 |
A fluorocopolymer film formed by molding at a molding temperature of at most 320° C. a fluorocopolymer comprising repeating units based on ethylene, repeating units based on tetrafluoroethylene, repeating units based on hexafluoropropylene and repeating units based on a fluoroalkyl vinyl ether represented by CF<SUB>2</SUB>-CFOR<SUP>f </SUP>(wherein R<SUP>f </SUP>represents a C<SUB>1-10 </SUB>fluoroalkyl group), having a molar ratio of the repeating units based on ethylene/the repeating units based on tetrafluoroethylene of from 10/90 to 60/40, a content of the repeating units based on hexafluoropropylene to the total repeating units of from 0.1 to 20 mol % and a content of the fluoroalkyl vinyl ether to the total repeating units of from 0.1 to 10 mol %, and having a volumetric flow rate of from 0.1 to 30 mm<SUP>3</SUP>/sec at 297° C.
