The laser-markable sheathing comprises a carbon-blacked inner PE layer with a soot proportion of 2.5±0.5% by weight and an outer PE layer 0.05 to 0.2 mm thick. The outer PE layer completely absorbs the laser radiation (lambda=532 nm) used for the marking, and the inner layer beneath it remains intact. A largely carbon-free, foamlike structure which greatly scatters incident light serves as an abrasion-proof marking. The sheathing is suitable for cable cores, fiber-optic cable strands, and the like. |
