Fluorkohlenstoffharz und Verfahren zu dessen Herstellung |
| 摘要 |
A process for treating polytetra fluoroethylene resin comprises heating polytetrafluoroethylene resin granules having a crystallinity of from 94 to 96% at a temperature of 325 DEG to 340 DEG C. to reduce the crystallinity of the resin to from 75 to 90%. The resultant polytetrafluoroethylene resin granules are said to be 10 to 50% sintered. |
