Abstract
A method of manufacturing a crosslinked fluororesin powder includes forming a powder mixture by mixing a fluororesin powder as a first powder with a second powder not fusing to the fluororesin powder even under conditions for crosslinking of the fluororesin powder, and conducting a cross-linking treatment to the formed powder mixture.
Claims12
A method of manufacturing a crosslinked fluororesin powder, comprising:
- forming a powder mixture by mixing a non-crosslinked fluororesin powder as a first powder with a second powder to provide a formed powder mixture;
- conducting a cross-linking treatment to the formed powder mixture by exposure to ionizing radiation in an oxygen-free atmosphere or in a low-oxygen atmosphere with not more than 500 ppm oxygen at a crosslinking temperature not less than a melting point of the first powder but lower than a melting point of the second powder;
- and
- separating the first powder and the second powder after the cross-linking treatment.
