Tetrafluoroethylene polymer for stretching |
摘要 |
A tetrafluoroethylene polymer having high stretchability, a fibrillatable character and a non-melt fabricable quality, which has a standard specific gravity of at most 2.160, and a tensile break strength of from 32.0 N (3.26 kgf) to 49.0 N (5.0 kgf) or an endothermic ratio of at most 0.15 as calculated from the measurement by differential thermal analysis. The tetrafluoroethylene polymer is suitable for stretching operation after paste extrusion.
