Abstract
The present invention aims to provide a fluorine-containing polymer powder that is environmentally less harmful and forms a sufficiently smooth film without impairing the properties of the fluorine-containing polymers. The present invention relates to a fluorine-containing polymer powder including a fluorine-containing polymer prepared by suspension polymerization, which contains less than 0.1 ppm of a fluorine-containing surfactant and has an average particle size of not less than 1 μm and less than 100 μm and a bulk density of 0.90 to 1.50 g/cm.
