Process for producing polytetrafluoroethylene molding powder |
| abstract |
A process for producing a polytetrafluoroethylene (hereinafter abbreviated to 'PTFE') molding powder comprising fine grinding of coarse PTFE particles in a wet state, which permits washing of PTFE in a finely ground state and efficient reduction in the impurity content of PTFE, and another process therefor by agglomerating and granulating the above finely ground and washed PTFE particles, which permits the production of a PTFE powder in less process steps. The former process is characterized in that coarse PTFE particles prepared by suspension polymerization of tetrafluoroethylene are finely ground in a wet state to form fine particles particularly having a mean particle diameter of 10 to 100 νm and and thereafter the resulting fine particles are washed, while the latter process is characterized in that the washed fine PTFE particles are agglomerated and granulated in a wet state by application of a mechanical force to form particles having a mean particle diameter of 200 to 800 νm. |
