Description

Technical field

[0001] The present invention relates to an optical cable sheathing material, especially a special material for color identification of color polyolefin special optical cable. Background technique

[0002] With the increase in the types of optical cables, different types of special optical cables need to be distinguished by extruding one or more color lines on the surface of the cable sheath. Nowadays, color masterbatch and polyethylene are simply mixed and then extruded to form color lines on the surface of the sheath. The color lines on the surface of the sheath have the following problems: First, the color line part and the sheath are poorly combined, which is easy Cracks and delamination occur, and weather resistance is also poor; second, it is easy to fade during use; third, there is a big gap between the performance of the color line part and the performance of the sheath part, resulting in a decrease in the performance of the entire optical cable.
