PTFE POWDER AND METHOD FOR PRODUCING PTFE POWDER FOR MOLDING

摘要

A polytetrafluoroethylene powder,characterized in that it provides a molded article for measurement(a1)having a surface roughness(Ra)of less than 0.92μm;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.
