改性聚四氟乙烯粉末和四氟乙烯聚合物的制造方法
摘要：
本发明提供改性聚四氟乙烯粉末以及四氟乙烯聚合物的制造方法。所述聚四氟乙烯粉末兼具成型加工性和微波波段中的电气特性。该改性聚四氟乙烯粉末的特征在于：(1)其在12GHz的介电损耗正切小于等于2.0×10-4，且(2)其在压缩比率为1600时的圆柱挤出压力小于等于45MPa。
摘要（英）：

Disclosed is a polytetrafluoroethylene powder having adequate formability and electrical characteristics in the microwave range at the same time. Specifically disclosed is a modified polytetrafluoroethylene powder which is characterized by having (1) a dielectric loss tangent of not more than 2.0 x 10<-4> at 12 GHz, and (2) a column extrusion pressure of not more than 45 MPa at a reduction ratio of 1600.
