RESIN COMPOSITION AND MOLDED BODY

Title:

RESIN COMPOSITION AND MOLDED BODY

Document Type and Number:

WIPO Patent Application WO/2023/182154

Kind Code:

A1

Abstract:

The present invention provides: a resin composition which is capable of forming a molded body that has excellent wear characteristics and heat resistance; and a molded body.　The present invention provides a resin composition which contains a thermoplastic non-fluorinated resin, a first tetrafluoroethylene polymer, and a second tetrafluoroethylene polymer which has a melting point that is not less than 260°C but less than the melting point of the first tetrafluoroethylene polymer. With respect to this resin composition, relative to the total mass of the thermoplastic non-fluorinated resin, the first tetrafluoroethylene polymer and the second tetrafluoroethylene polymer, 4.0-32.0% by mass of the first tetrafluoroethylene polymer and 0.5-10.0% by mass of the second tetrafluoroethylene polymer are contained; and this resin composition is obtained by melt-kneading a powder of the thermoplastic non-fluorinated resin and a mixed powder of first particles of the first tetrafluoroethylene polymer and second particles of the second tetrafluoroethylene polymer.
