Adhesive lined heat shrink tubes ТТК 4:1 - a new generation of heat shrinkage of the XXI century rightfully occupies its niche among the adhesive heat shrink tubes, with a shrink ratio- 4:1, for insulation, corrosion protection and sealing of electrical connections.
Tubes ТТК are made from a special composition of polyolefins with the addition of non-toxic flame retardant, harmless to human.
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.
The presence of the adhesive layer ensures reliable sealing of any contact joints and gives them additional mechanical strength after shrinkage. Melting and filling all the irregularities of the microrelief by hot-melt glue makes the cable assembly as monolithic leakproof structure.
The increased shrink ratio allows using of heat shrink tubes TTK 4:1 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 4:1 are supplied in convenient packing by 10 pieces (meter cutting) and presented in optimal size range, from 4/1 to 52/13 mm.
