    • A thin, lightweight insulated wire comprises a core (10) with an insulating polymeric sheath comprising an inner layer (12) of polytetrafluroethylene (PTFE) to empower electrical insulation, a middle layer (14) of an aromatic and/or heterocyclic ring-containing polymer such as polyetheretherketone(PEEK) to provide enhanced mechanical properties such as abrasion and cut-through resistance and an outer layer (16) of PTFE which provides electrical and chemical resistance and allows the whole construction to be sintered. The middle layer may undergo some flow and alloying during sintering, which may provide additional and unexpected benefits. The preferred thickness of each film is 25 to 50 μm. The use of such thin films allows for a compact, thin and lightweight insulation to be produced.
    • 一种薄而轻的绝缘电线包括具有绝缘聚合物护套的芯体(10),其包含聚四氟乙烯(PTFE)的内层(12)以赋予电绝缘性,含有芳族和/或杂环的中间层(14) 诸如聚醚醚酮(PEEK)的聚合物,以提供增强的机械性能如耐磨性和耐穿透性,以及提供耐电化学性和允许整个结构烧结的PTFE的外层(16)。 中间层在烧结过程中可能会发生一些流动和合金化,这可能会提供额外的和意想不到的好处。 每个膜的优选厚度为25至50μm。 使用这种薄膜可以生产紧凑,薄而轻的绝缘体。
