Heat shrinkable tube in special Т-ВОХ (Т-бокс) - standard high quality tubes (ТНТ нг) with shrink ratio 2:1, do not support combustion (self-extinguishing) in a special compact pack -by 10 meters. Tubes are made of improved polyolefin composition 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.

Improved composite structure of tube ТНТ нг, while maintaining the incombustibility and nontoxicity, has allowed getting greater flexibility and elasticity, lower shrinkage temperature (70°-80°C) and reduced smoke. Tube ТНТ нг, produced by “KBT” factory are halogen-free and comply with international ROHS standard.

Heat shrink tubing ТНТнг (КВТ) have strong properties of slow burning and is recommended for installation on modern wires and self-extinguishing cables (with index "нг" and "нг LS"). Low threshold of temperature while shrinkage (70°C), enables rapid and convenient installation of the tube. The material of the tubes is resistant to UV rays and weather conditions.

Tube ТНТнг (КВТ) supplied by 10 meters, in a compact special design cardboard Euro-boxes. For easy pulling of the tube out of the box, there are special window and inner rotating coil provided. This packing is perfect for displaying goods in shops and easy to store.

The range of sizes is optimal for retail customers: from 4/2 to 20/10mm. Small dimensions tubes -up to 6/3mm (including) have round shape. Tubes with diameter - 8/4mm and more have flat shape.

Being already widely known among professionals, “KBT” heat shrink tubing is getting closer and closer to ordinary consumers, gradually acquiring the title of national brand.
