Application

由于其化学惰性和疏水性,PTFE被广泛用于外科网状敷料、支架、移植物和韧带修复支架。比如,膨体PTFE可被用于制备血管移植物。

PTFE在宽频率范围和高介电强度下仍能保持介电常数恒定,这使得它是做电缆绝缘和高温储能应用的合适材料

它还可被作为易清洁、有化学惰性和不粘的涂层应用于食品、化工和制药领域。

Features and Benefits

  • 高耐化学性
  • 低摩擦系数
  • 柔韧性
  • 高热稳定性

General description

PTFE是四氟乙烯的合成氟聚合物。由于它是一种完全由碳和氟组成的高分子量化合物,因而它是一种碳氟化合物固体。PTFE本质上是疏水性的,它对任何固体都具有最低的摩擦系数。
