Abstract

Disclosed is a method for producing a PTFE molded article, which enables to make the thickness of a PTFE molded article extremely thin, while having an extremely low extrusion pressure during extrusion molding. Specifically disclosed is a method for producing a polytetrafluoroethylene molded article, which is characterized by comprising a step for extrusion molding a dispersion liquid of primary particles of polytetrafluoroethylene.
