摘要：
The present invention provides a modified polytetrafluoroethylene fine powder which can be processed into molded articles high in thermal stability, chemical resistance and transparency and for which the extrusion pressure can be lowered. The present invention is a modified polytetrafluoroethylene fine powder, wherein the cylinder extrusion pressure at a reduction ratio of 1600 is not higher than 50 MPa and the haze value of molded article a for measurement formed therefrom is not higher than 60.
