  • Publication number: 20220332025
    Abstract: A composition containing a melt-moldable fluororesin having a 1% decomposition temperature of 300° C. or higher and a thermotropic liquid crystal polymer, 90 mol % or more of all repeating units of the thermotropic liquid crystal polymer having an aromatic structure. The fluororesin is contained in an amount of 99.99 to 97% by mass and the thermotropic liquid crystal polymer is contained in an amount of 0.01 to 3% by mass relative to the composition. Also disclosed is an injection-molded article and a molding aid for injection molding fluororesin.
