 Tubes  ТУТнг -  standard high quality heat shrink tubes with shrink ratio 2:1, do not support combustion (self-extinguishing). Made of a special composition of polyolefin with the addition of non-toxic flame retardants.

 A unique feature of these type “KBT” production tubes- is the adjusted uniform wall thickness, which is achieved through careful control of technological processes of extrusion and extension. In addition, unlike Chinese production heat-shrink tubing, widely represented on the Russian market, the thickness of the tubes ТУТ нг “KBT” is much more than the budget low-quality counterparts. High demands on the insulating properties and reliability of products distinguish “KBT” heat shrink products from others.

 Heat shrink tubes ТУТ нг “KBT” are non-flammable, environmentally friendly and harmless to humans.

 Composition of tubes contains substances retarding combustion. “KBT” factory is the first producing factory in the country, developed a special composition. As a result of this development, to the familiar acronym ТУТ (Heat Shrinkable Tube) were added incombustibility index -"нг". Tubes ТУТнг (КВТ) have strong properties of slow burning and are recommended for installation on modern wires and cables with self-extinguishing insulation (with index «нг» and «нг LS»).

 Low temperature threshold while shrinkage (90°) provides the speed and ease of installation. The material of the tubes is resistant to UV rays and weather conditions.

 Tubes ТУТнг (КВТ) are supplied in rolls and ideal for industrial applications, suggesting cutting to the required size at the installation site. The range of sizes is very wide and has 7 standard colors (black, red, yellow, blue, green, white and yellow-green). Under the special order, custom colors could be provided. Small sizes tubes, including size 6/3mm have round shape and tubes with a diameter 8/4mm and more have flat shape.

 Black color heat shrink tubes have the most wide size range, starting from 2/1 to 120/60mm. Color tubes diameter vary from 4 to 60mm.

 Tubes ТУТнг (КВТ) for many years, successfully used in various fields of domestic industry: for performing electrical work, home repairing, Auto and Moto equipment, for marking and banding of wires, corrosion protection of electrical connections, as well as decorative purposes
