WIPO Patent Application WO/2020/149097
Kind Code:
A1
Abstract:
[Problem] To provide a dry powder which is a blend of different kinds of tetrafluoroethylene polymer powders and uses a powder of a tetrafluoroethylene polymer that has an oxygen-containing polar group, and wherein the physical properties of the respective polymers are highly exhibited. [Solution] A dry powder according to the present invention contains a tetrafluoroethylene polymer and a fluoropolymer which has an oxygen-containing polar group and a unit that is based on tetrafluoroethylene. It is preferable that the fluoropolymer has a melting point of from 140°C to 320°C. It is also preferable that the fluoropolymer contains a unit that is based on a monomer having the oxygen-containing polar group.
