<p>A wire or cable comprises a core (10) and a sheath including a wrapped film (16) of polyetherether ketone (PEEK) and a flameproofing layer (14) comprising mica particles dispersed in a polymer matrix such as a silicone. An outer coating (18) of PEEK or another polymer may be provided, which may be sintered to provide a tough outer protective covering. The PEEK and mica layers combine synergistically to provide a sheath of increased flame resistance as well as high flexibility and resistance to mechanical stresses, while being of reduced weight and diameter.</p> |
