Adhesive lined heat shrink tubes ТТК 3:1 - are high quality and popular type in adhesive lined heat shrink tubes, with a shrink ratio- 3:1, for insulation and sealing of electrical connections.
Tubes ТТК are made from a special composition of polyolefins with the addition of non-toxic flame retardant (except transparent tubes), which gives them distinct properties of incombustibility.
Typical and distinctive feature of this type of tubes- is hot melt adhesive layer, uniformly applied on the entire inner surface of the tube by coextrusion, which provides a reliable sealing of all contacts with voltage up to 1000V and gives them additional mechanical strength after shrinkage. Adhesive melting and filling of all irregularities transforms cable assembly in a solid sealed structure.
The increased shrink ratio allows using of heat shrink tubes TTK 3:1 for mounting on cables and strands with significant levels differences and complex shapes, while maintaining flexibility and elasticity of the assembly.
After melting and cooling the adhesive composition of tubes TTK provides excellent adhesion to almost any surfaces and materials. However, before installation, during storage and transportation, adhesion of layer is minimal, which prevents adhesion of the tubes one to each other.
Adhesive lined heat shrink tubes TTK have high resistance to UV, weather conditions and approved for outdoor installation in areas with high humidity levels, as well as for installation directly into the ground and concrete.
TTK shrink tubes 3:1 are supplied in convenient packing by 10 pieces (meter cutting) and presented in optimal size range, from 3/1 to 50/17.
Long-term use of TTK tubes in various sectors of domestic industry (electrical work, military industrial complex) proves good quality and reliability.
