A composite coating includes a first layer, a second layer, and a fluoropolymer film disposed on the second layer. The first layer includes a polymer matrix with mica particles dispersed throughout, while the second layer includes a polyether ether ketone (PEEK).

High temperature insulating tape and wire or cable sheathed therewith

A wire or cable comprises a core () and a sheath including a wrapped film () of polyetherether ketone (PEEK) and a flameproofing layer () comprising mica particles dispersed in a polymer matrix such as a silicone. An outer coating () 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.

High performance, high temperature wire or cable

Primary wire for marine or undersea cable comprises a conducting core (), typically a multifilament core of copper, and an insulating sheath comprising an insulating inner layer () having a thickness of 0.35 to 1.0 mm, preferably 0.5 to 0.75 mm, and an outer protective layer () of polyvinylidene fluoride having a thickness of 0.15 to 0.3 mm, at least the outer layer being radiation crosslinked. The inner and outer layers are preferably crosslinked together using electron beam radiation. The combination of the inner and outer layers of the sheath enables marine and subsea cables and the like to be made with smaller diameters, without loss of capacity or electrical properties and with an increase in overall performance such as temperature range and mechanical properties.
