聚四氟乙烯(F4，PTFE)具有一系列优良的使用性能：耐高温—长期使用温度200~260度，耐低温—在-100度时仍柔软；耐腐蚀—能耐王水和一切有机溶剂；耐气候—塑料中最佳的老化寿命；高润滑—具有塑料中最小的摩擦系数（0.04）；不粘性—具有固体材料中最小的表面张力而不粘附任何物质
PTFE密度较大，为2. 14一2. 20g/cm3，几乎不吸水，平衡吸水率小于0. 01%。
聚四氟乙烯是典型的软而弱聚合物，大分子间的相互引力较小，刚度、硬度、强度都较小，在应力长期作用下会变形。
聚四氟乙烯受载时容易出现蠕变现象，是典型的具有冷流性的塑料。PTFE的蠕变随压缩应力、温度和结晶度的不同而异，温度越高则蠕变越大。PTFE的结晶度在55%一80%之间，蠕变量不超过2%;当结晶度在55%以下和80%以上时，蠕变量迅速增大。
聚四氟乙烯力学性能方面优异的特性是摩擦因数小，在0. 01一0. 10之间，在现有塑料材料，乃至所有工程材料中最小。
PTFE的摩擦因数随滑动速率的增大而增大，当线速度达到0. 5一1. 0m/s以上时趋于稳定;而且静摩擦因数小于动摩擦因数，将这种特性用于轴承制造，可减小其起动阻力，使之从起动到运转都十分平稳。PTFE的摩擦因数随随载荷增加而减小，当载荷达到0. 8 MPa以上时趋于恒定。在高速、高载荷下，PTFE的摩擦因数低于0. 01。从超低温到PTFE熔点.
