Abstract

Provided are a fluororesin composition having a low electrostatic propensity, and a fluororesin molded article having a low electrostatic propensity that is configured from a fluororesin composition. A thermoplastic fluororesin composition that comprises a fluororesin, two or more kinds of vinylidene fluoride-tetrafluoroethylene-hexafluoropropylene terpolymers and an ionic liquid, wherein said terpolymers include a terpolymer selected from among terpolymers containing 30-45 mol % of vinylidene fluoride and a terpolymer selected from among terpolymers containing 5-25 mol % of vinylidene fluoride; and a fluororesin molded article.

First claim

What is claimed is:

1. A thermoplastic fluororesin composition comprising:
a fluororesin;
two kinds of vinylidene fluoride-tetrafluoroethylene-hexafluoropropylene terpolymers; and
an ionic liquid,
wherein the terpolymers include at least one terpolymer containing 30-45 mol % of vinylidene fluoride and at least one terpolymer containing 5-25 mol % of vinylidene fluoride, and wherein a content of the vinylidene fluoride is a value calculated by a 19F-NMR method.

2. The thermoplastic fluororesin composition according to claim 1 , wherein the fluororesin is tetrafluoroethylene-perfluoroalkylvinylether copolymer or tetrafluoroethylene hexafluoropropylene copolymer.

3. The fluororesin composition according to claim 1 , wherein the terpolymer containing 30-45 mol % of vinylidene fluoride and the terpolymer containing 5-25 mol % of vinylidene fluoride are contained in a total amount of 0.1% by mass to 10% by mass.

4. The fluororesin composition according to claim 1 , wherein the ionic liquid has a heterocyclic ring.

5. The fluororesin composition according to claim 1 , wherein the ionic liquid is contained in the amount of 0.01% by mass to 1% by mass in the fluororesin composition.
