METHODS FOR PREPARING AGGLOMERATED PELLETS OF POLYTETRAFLUOROETHYLENE AND MOLDED ARTICLES THEREOF |
| 摘要 |
PTFE pellets with good bulk density, homogeneity, and flowability properties may be obtained by: (1) wetting a PTFE powder with a solvent, to obtain a wetted PTFE powder; (2) forming the wetted PTFE powder into agglomerated pellets of PTFE; and (3) drying the agglomerated pellets of PTFE pellets, in which the drying of the agglomerated pellets of PTFE is carried out in a fluidized bed drier. The PTFE pellets so obtained may be used to prepare molded articles of PTFE. |
