PURPOSE:To obtain a fluorocarbon polymer composition which has an insulating property but yet shows weak chargeability, excels in heat resistance, etc., and is useful in the field of electronic components, etc., by mixing a fluorocarbon polymer with a finely powdered positively chargeable inorganic filler. CONSTITUTION:60-95wt% fluorocarbon polymer (A) such as a vinylidene fluoride/hexafluoropropylene copolymer or an ethylene/tetrafluoroethylene copolymer is mixed with 40-5wt% positively chargeable inorganic filler (B) of an average particle diameter <=5mu to obtain the purpose fluorocarbon polymer composition. Examples of component B include fine powders of magnesium oxide, zinc oxide and aluminum oxide. It is also possible to add a small amount of a positively chargeable silicone oil, a negatively chargeable fluorocarbon oligomer or the like in order to improve the moldability, compatibility with the inorganic filler or the like properties.
