摘要:
The present invention provides a polytetrafluoroethylene powder having moldability/processability as well as electrical characteristics in microwave bands. The present invention is a modified polytetrafluoroethylene powder which has (1) a dielectric loss tangent at 12 GHz of not higher than 2.0×10−4 and (2) a cylinder extrusion pressure of not higher than 45 MPa at a reduction ratio of 1600.
