PTFE物理性能

聚四氟乙烯(PTFE)具有化学稳定性，对人体无毒副作用，对热和化学品具有高抵抗力，并且具有极低的弹性模量。因此，PTFE可以应用于医疗设备中。

聚四氟乙烯(PTFE)具有化学稳定性，对人体无毒副作用，对热和化学品具有高抵抗力，并且具有极低的弹性模量。因此，PTFE可以应用于医疗设备中。这篇研究聚焦于PTFE作为假体及牙科设备/器械相关的物理特质。结果显示，与其他样本相比（除了磨损和着色测试下的瓷材料），PTFE展现出低磨耗性(大约是牛牙的1/3以及III型合金的1/2)、低摩擦性(大约为其他样本的1/5)、低硬度(4.8HV1.0)、低着色和较少的细菌粘附(p<0.01)。这些结果表明，PTEF可以应用于一些临时和/或永久使用的假体，为牙科器械/设备提供高性能的抗吸收性，为保持咬合垂直尺寸和原始功能提供高耐磨性，并且易于清洁。原始出处：Kameda T， Ohkuma K， et al.
