Abstract

Cables include a conductor core and an insulative wall. The insulative wall is generally ultra-thin, and may have a thickness of from about 0.10 mm to about 0.44 mm. The insulative wall includes a flame retardant additive and is essentially halogen free.

Description

technical field [0001] The present invention relates to cables and wires, especially cables made of halogen-free materials. Background technique [0002] Cables for conductive or optical fiber transmission generally have insulating walls to protect the cables. This insulating wall is usually a bendable and wear-resistant non-conductive plastic. Plastic walls have disadvantages, however, because they can emit harmful gases or intensify a fire when they burn. [0003] Flame retardant plastics can be made using halogenated materials, especially bromides. However, the use of flame-retardant plastics increases health and environmental stress. The use of non-halogenated flame retardants in plastics also generally has disadvantages due to the large amounts of non-halogenated flame retardants required to achieve effective flame retardancy. [0004] Without the use of halogen compounds, it is difficult to achieve the insulation of ultra-fine cables. Therefore, there is a need fo...
