Transparent adhesive lined heat shrink tubes 3:1 without suppression of burning

type : ТТК(3:1)

  • Designed for sealing, insulation, and corrosion protection of contact connections in power generation and telecommunications
  • Advanced shrink ratio: 3:1
  • Material: polyolefin
  • Color: transparent
  • All inner surfaces of heat shrinkable tubes has a hot-melt adhesive layer, applied by coextrusion
  • Tubes ensure visual control of contact joints after shrinkage
  • While shrinkage, adhesive layer melts, and fills all the irregularities and provides full leak proofness of connections
  • Packing: cutting by 1-meter length

Transparent adhesive lined heat shrink tubes ТТК 3:1 - “KBT” high quality and popular type tubes, made from modified polyolefin, halogen-free, without suppression burning, with shrink ratio 3:1, for insulation and sealing of electrical connections.

Transparent adhesive lined heat shrinkable tubes TTK 3:1 possess all the properties of standard heat shrinkable tubes TTK 3:1 (special adhesive, based on Eva with excellent adhesion, ease of working with complex shapes, flexibility, elasticity, UV resistance, etc.), except for the suppression of combustion.

Smooth glossy surface and full visibility of adhesive lined heat shrinkable transparent tubes TTK 3:1 provides the opportunity for visual inspection of contact joints after shrinkage and isolation.

Transparent adhesive lined heat shrinkable tubes TTK are weather resistant and approved for outdoor installation and indoor installation with high moisture level, for long-term anti-vandal protection of marking tags and nameplates, imposed on cables and wires, and to ensure visual control over the location of the contact connection, while maintaining integrity.

Transparent adhesive lined heat shrinkable tubes TTK 3: 1 (KBT) are supplied in meter cutting- convenient package by 10 pieces and are represented by the optimal size range – from 4.8/1.6 to 39/13.

Long-term use of TTK tubes in various sectors of domestic industry (electrical work, military industrial complex) proves good quality and reliability
