More Information
Summary:A method for removing metallic foreign matter from a fluororesin and a method for producing a fluororesin with reduced metallic foreign matter, which methods include applying a magnetic field to a fluororesin with a magnet while dropping the fluororesin by gravity to thereby remove metal, wherein the methods provide a screen made of a magnetic material in a flow path of the fluororesin dropped by gravity, and when the fluororesin passes through the screen, the screen is not vibrated.
