摘要: Finely ground polytetrafluoroethylene molding powder with or without a filler is subjected to high speed agitation in the presence of a medium consisting essentially of water and a hydrophobic organic liquid at a ratio of 0.5 to 1 liter per 1 Kg of the resin to agglomerate it. Hydrophobic organic liquids mean organic liquid which dissolve less than 15 wt. % in water at the temperature of agglomeration.The volumetric ratio of the organic liquid to water is in a range of 2 to 1/2.The agglomerated product having narrow particle size distribution and high bulk density and free flowing property can be obtained by the agitation for short time.
