<p>A polytetrafluoroethylene powder, characterized in that it provides a molded article for measurement (a1) having a surface roughness (Ra) of less than 0.92 μm; and a method for producing the polytetrafluoroethylene powder for molding. The polytetrafluoroethylene powder can provide a molded article which is improved in surface roughness (Ra), tensile strength and/or tensile elongation and also is better in dielectric breakdown strength over a conventional such an article, and optionally, in addition to the above, it is excellent in its bulk density and/or powder fluidity.</p> |
