聚四氟乙烯(PTFE)具有耐高温特点，使用工作温度达250℃。在较宽频率范围内的介电常数和介电损耗都很使用的表面缺陷。affecting the use.
低，而且击穿电压，体积电阻率和耐电弧性都较高，是理想的PCB板材料
Polytetrafluoroethylene(PTFE)has the characteristics of high temperature resistance, and the operating temperature reaches 250 C. In a wide frequency range, the dielectric constant and dielectric loss are very low, and the breakdown voltage, volume resistivity and arc resistance are high, so it is an ideal PCB material.
