優(yōu)點
耐高溫——使用工作溫度達(dá)250℃。
耐低溫——具有良好的機(jī)械韌性；即使溫度下降到-196℃，也可保持5%的伸長率。
耐腐蝕——對大多數(shù)化學(xué)藥品和溶劑，表現(xiàn)出惰性、能耐強(qiáng)酸強(qiáng)堿、水和各種有機(jī)溶劑。
耐氣候——有塑料中的老化壽命。
高潤滑——是固體材料中摩擦系數(shù)低者。
不粘附——是固體材料中小的表面張力，不粘附任何物質(zhì)。
無毒害——具有生理惰性，作為人工血管和臟器長期植入體內(nèi)無不良反應(yīng)。
聚四氟乙烯相對分子質(zhì)量較大，低的為數(shù)十萬，高的達(dá)一千萬以上
不足
1、聚四氟乙烯具有“冷流性”。即材料制品在長時間連續(xù)載荷作用下發(fā)生的塑性變形(蠕變)，這給它的應(yīng)用帶來一定的限制。如當(dāng)PTFE用作密封墊時，為密封嚴(yán)密而把螺栓擰得很緊，以致超過特定的壓縮應(yīng)力時，會使墊圈產(chǎn)生“冷流”(蠕變)而被壓扁。這些缺點可通過加入適當(dāng)?shù)奶盍霞案倪M(jìn)零件結(jié)構(gòu)等方法來克服。
2、PTFE具有突出的不粘性，限制了其工業(yè)上的應(yīng)用。它是極好的防粘材料，這種性能又使它與其他物件的表面粘合極為困難。
3、PTFE的線膨脹系數(shù)為鋼的10~20倍，比多數(shù)塑料大，其線膨脹系數(shù)隨著溫度的變化而發(fā)生很不規(guī)律的變化。在應(yīng)用PTFE時，如果對這方面性能注意不夠，很容易造成損失。
