Abstract
To provide a fluorine-containing resin composition useful as a molding material for parts of electronic and electrical equipment which assures well-balanced enhancement of dielectric property, heat resistance, mold-processability (precise processability) and mechanical properties and the parts of electronic and electrical equipment. The fluorine-containing resin composition for parts of electronic and electrical equipment comprises 70 to 95% by weight of (I) fluorine-containing resin mixture comprising (a) a fluorine-containing resin containing polytetrafluoroethylene not to be fibrillated and (b) a thermoplastic resin other than the fluorine-containing resin and 5 to 30% by weight of (II) a metal compound whisker having a single bond strength of not less than 190 KJ/mol calculated from a dissociation energy of bond between a metal element and oxygen. The parts of electronic and electrical equipment which are obtained from the composition have a dielectric constant of not more than 3.5.
