Abstract
To provide a method of shaping a granular polytetrafluoroethylene powder, in which a powder flowability can be enhanced and an apparent density can be increased without substantially changing an average particle size and particle size distribution of the powder. The granular polytetrafluoroethylene powder having an average particle size of 100 to 800 &mgr;m is subjected to shaping by using a rotating-type stirring vessel with two cross axes.
