MODIFIED POLYTETRAFLUOROETHYLENE POWDER AND METHOD FOR PRODUCING TETRAFLUOROETHYLENE POLYMER
摘要
<p>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 x 10 -4 and (2) a cylinder extrusion pressure of not higher than 45 MPa at a reduction ratio of 1600.</p>
