    Abstract: The invention provides a polytetrafluoroethylene composition having high flowability. The polytetrafluoroethylene composition contains a particulate polytetrafluoroethylene having fibrillability and a particulate synthetic amorphous silica. The particulate polytetrafluoroethylene is a polytetrafluoroethylene fine powder or a polytetrafluoroethylene molding powder. The particulate synthetic amorphous silica is obtained by a dry process and has an average primary particle size smaller than 200 nm. The particulate synthetic amorphous silica is attached to the surface of the particulate polytetrafluoroethylene.
