| titleOfInvention |
Modified polytetrafluoethylene molded article and process for manufacture thereof |
| abstract |
It is an object of the present invention to obtain a PTFE molding excellent in flexing resistance without decreasing the tensile strength and tensile elongation. The present invention is a modified polytetrafluoroethylene molded article obtained by molding a modified polytetrafluoroethylene molding powder, wherein the modified polytetrafluoroethylene molding powder is not melt-moldable, the modified polytetrafluoroethylene constituting the modified polytetrafluoroethylene molding powder contains 0.01 to 1% by mass of a perfluorovinyl ether unit represented by the formula (I): n n(wherein X is a perfluoroalkyl group containing 1 to 6 carbon atoms or a perfluoroalkoxyalkyl group containing 4 to 9 carbon atoms) and the heat of crystallization thereof is 18.0 to 25.0 J/g as measured using a differential scanning calorimeter, and the modified polytetrafluoroethylene molded article has a heat of fusion of not more than 28 J/g and a flex life of at least 200×10 4 cycles. |
