Adhesive heat shrink tubing TTK(3:1)-40/13 red 84875 KVT

• Designed for sealing, insulation, marking, and corrosion protection of contact connections in power engineering and telecommunications • Expanded shrink ratio: 3:1 • Material: polyolefin, flame retardant • Color: red • A layer of hot-melt adhesive is applied to the entire inner surface of the heat-shrink tubes by co-extrusion • Upon shrinking, the adhesive layer melts, fills all micro-relief irregularities, and ensures complete sealing of the connections • Supply form: 1 m lengths • Installation tools: TT series high-temperature heat guns, PG propane torches, "KVT" portable butane torches Product description and features TTK 3:1 adhesive tubes are high-quality and popular heat-shrink adhesive tubes from "KVT" with a 3:1 shrink ratio for insulating and sealing electrical connections. TTK tubes are made from a special polyolefin composition with the addition of non-toxic flame retardants (except for transparent tubes), which give them pronounced non-flammable properties. A characteristic and distinguishing feature of this type of tube is a layer of hot-melt adhesive uniformly applied to the entire inner surface of the tubes by co-extrusion, the presence of which ensures reliable sealing of any contact connections up to 1000V and provides additional mechanical strength after shrinking. By melting and filling all micro-relief irregularities, the hot-melt adhesive turns the cable assembly into a monolithic, airtight structure. The increased shrink ratio allows the use of TTK 3:1 heat-shrink tubes for installation on cables and splices with significant level differences or complex profiles while maintaining the flexibility and elasticity of the assembly. After melting and cooling, the adhesive composition of the TTK tubes provides excellent adhesion to almost any surfaces and materials. However, before installation, during storage and transportation, the adhesion of the Savilen composite adhesive layer is minimal, which prevents the tubes from sticking together. TTK adhesive heat-shrink tubes have high resistance to ultraviolet radiation and weather conditions and are approved for outdoor installation, in high-humidity rooms, as well as for installation directly in soil and concrete. Recently introduced size range of non-flammable TTK (KVT) tubes in black has been supplemented with red and white tubes. This significantly increases their scope of application, allowing the use of different colored tubes (e.g., red and black) for "phase-neutral" marking in battery chargers and other devices. TTK 3:1 (KVT) heat-shrink tubes are supplied in 1-meter lengths in convenient packaging of 10 pieces and are presented in an optimal size range – from 3/1 to 50/17. The many years of application of TTK tubes in various fields of domestic industry, from electrical installation work to use in the military-industrial complex, best speaks to the quality and reliability of this development.
