摘要：
This invention provides a polytetrafluoroethylene powder capable of giving moldings which are improved in surface roughness Ra tensile strength and/or tensile elongation as compared with the prior art ones and can be excellent in dielectric breakdown strength and, further, can be excellent, if desired, in apparent density and/or powder flowability as well, and a method of producing a polytetrafluoroethylene molding powder.The present invention is a PTFE powder wherein a surface roughness Ra of molded articles a1 for measurement is less than 0.92 μm.
