Title:
Polytetrafluoroethylene water dispersion liquid and polytetrafluoroethylene fine powder
Document Type and Number:
Japanese Patent JP6241528
Kind Code:
B2
Abstract:
The present invention aims to provide a polytetrafluoroethylene aqueous dispersion which contains significantly minute polytetrafluoroethylene particles and which is excellent in dispersion stability, and a significantly minute polytetrafluoroethylene fine powder. The polytetrafluoroethylene aqueous dispersion contains polytetrafluoroethylene particles including a tetrafluoroethylene unit alone or a tetrafluoroethylene unit and a modifying monomer unit derived from a modifying monomer copolymerizable with the tetrafluoroethylene unit. The polytetrafluoroethylene particles have a volume average particle size of not smaller than 0.1 nm but smaller than 20 nm.
