应用
聚四氟乙烯绝缘体 PTFE 在很宽的温度和频率范围内具有优异的电气绝缘性能。由于 PTFE 分子链中的氟原子是对称均匀分布的,不存在固有偶极矩,因此介电损耗正切 TGA 和相对介电常数较小,ER 随温度升高而减小。聚四氟乙烯绝缘体可用于滤波器、连接器等相关器件,在通信领域,5G 通信飞棒、支撑底座等绝缘体已得到深度应用。
此外还有绝缘聚四氟乙烯套管,材料:原生级和填充级聚四氟乙烯填料:玻璃纤维/碳/青铜/石墨/MoS2,以提高耐磨性和其他机械性能。内衬聚四氟乙烯管道是为腐蚀性危险和高价值工艺定制的。
细节和部件
我们展示的产品有不同尺寸,也可根据要求定制尺寸。
优点
- 绝缘电阻;PTFE 具有极高的绝缘电阻。其体积电阻率 PV 一般大于 1015ΩM,表面电阻率 PS 大于 1016Ω。
- 击穿场强;PTFE 的击穿场强非常高,极薄的 PTFE 薄膜的击穿场强可达 200KV/MM,但随着厚度的增加,击穿场强逐渐减小。
- 耐电弧性;PTFE 对电弧极为稳定,耐电弧性通常大于 300S。这是因为在高压表面放电时,它不会因碳化导致短路而分解成气体。即使长期暴露在露天环境中,受到灰尘和雨水的污染,也不会影响其绝缘性能。但由于聚四氟乙烯中氟原子的电负性较高,1~2EV 电子会使其离解分解,因此其抗电晕性能不好。
