Marking tubes ТТ-М нг – “KBT” factory new development. Heat shrink tubes ТТ-М нг have a shrink ratio - 2:1, do not support combustion and are designed for marking of wires and cables.

Tube ТТ-М нг  is designed to mount on modern self-extinguishing wires and cables with index "нг" and "нг LS". Specially treated surface provides high-quality marking by thermal transfer printing.

“KBT” factory produces marking tubes ТТ-М нг, made from polyolefin compositions, with addition of retarding combustion substances. This composition provides self extinguishing property (index, "нг") while absence of direct impact of flame on the surface of the tubes.

Heat shrink tubes for marking ТТ-М нг (KBT) supplied in rolls and are perfectly suited for industrial applications, suggesting cutting to the required sizes, at the time of applying marking by thermal printers. Sizes range from 4/2 to 12/6mm. Tubes of small dimensions (up to 6/3mm -including) have round shape, and  tubes with  diameter from 10/5 and 12/6mm have flat shape.

According to international standards, color of marking ТТ-М нг tubes- is yellow. On a request, it is possible to produce white color ТТ-М нг tubes.
