Process for producing granular polytetrafluoroethylene powder |
| abstract |
The process for preparing a granular polytetrafluoroethylenenpowder by using a non-flammable bromine-containing organic solventnhaving a boiling point of 0 to 150°C, particularly 1-bromopropane as annorganic liquid. According to the preparation process, it is possible tonexhibit granulation performance equal to a flon type organic solventnwhich gives particularly excellent performance, to provide a granularnPTFE powder being excellent in powder characteristics safely at low cost,nand to contribute to lowering of depletion of the ozone layer andnprevention of global warming. |
