An insulating coating material including a polyimide film, and an adhesion layer on at least one side of a polyimide film. The polyimide film has a weight of 23.5 g or less per 1 m.sup.2 and a loop stiffness value of 0.45 g/cm or more

The present invention is a flame-retardant polyolefin/thermoplastic polyurethane formulation made from or containing a polyolefin, a thermoplastic polyurethane, and an intumescent, polyphosphate flame retardant composition. The invented system achieves elongations >400% and tensile strengths >1500 psi while the same polyolefin only achieved 100% elongation and <1000 psi tensile strength. Also, the present invention shows improved tape extrusion performance versus a comparable TPU only composition, indicating improved melt rheology/fabrication capability for extrusion applications.

A stranded conductor (2) including a specific number of a first type of wire (5) which, in cross-section of the stranded conductor, are arranged in a hexagonal pattern around a central wire in at least two layers. The wires arranged at the vertices of the hexagonal pattern are of a second type of wire having in principle a smaller diameter than the first type of wires. The interstitial spaces (10) between the first and the second wires are filled by a sealing agent (3).

An optical electronic device comprises: a casing having an external surface provided with an opening; a cable inserted through the opening; a bush attached to the cable; and a resin sealing portion. The bush is brought into close contact with the cable and the casing to seal a gap between the cable and the casing. The resin sealing portion is provided locally inside the casing to cover an internal surface of a portion of the casing surrounding the opening and a surface of a portion of the cable drawn from the opening into the casing.
