PURPOSE:To provide a coloration method whereby a PTFE molding can be effectively colored so as to be discriminable without detriment to the inherent properties. CONSTITUTION:A molding powder prepared by homogeneously mixing 1-5wt.% colored tetrafluoroethylene resin granules, prepared by homogeneously mixing a tetrafluoroethylene resin with 0.1-5wt.% colorant, with 95-99wt.% colorant-free noncolored tetrafluoroethylene resin granules is used. Thus, even when the amount of the colorant is about 0.001-0.25wt.%, the molding made from the molding powder can be colored so as to be discriminable without detriment to the properties. Therefore, the administration of parts can be efficiently performed. |
