Abstract
Process for producing fluorine-containing polymer powder which comprises densifying fluorine-containing polymer raw powder with rolls under conditions for permitting its specific gravity to achieve at least 90% of the true specific gravity, then comminuting the densified material, removing fine particles in the range of 3 to 40% by weight of the whole particle size distribution of the comminuted material by air classification, and further removing by classification coarse particles in the range of 1 to 20% by weight of the whole particle size distribution of the comminuted material. Powder can be used as a powder paint which is excellent in productivity, in powder fluidity, and which does not generate pollution upon heat-fusion.
