Adhesive Lined Medium Wall Heat Shrink Tubing

Model: CYG-MWTA

Material
Exterior layer: irradiated cross-linked modified polyolefin
Inner layer: hot-melt adhesive

Shrink ratio: 3.5:1, 4:1

Applications
This medium wall polyolefin heat shrink tubing has an excellent insulation and mechanical protection performance. The tubing has higher shrink ratios to make it suitable for splicing of accessories and wires in a wide range of sizes. This heat shrink tubing also features a thicker wall, allowing it to offer insulating and mechanical protection for connectors in medium and high voltage cables. In addition, the hot melt adhesive inner layer offers a water resistant seal for all connecting accessories.

Features
  • This dual wall heat shrink tubing is covered in a black layer, thus giving it an excellent UV resistance.
  • The minimum full recovery temperature of this dual wall heat shrink tubing is 135℃. When the environmental temperature is higher than 135℃, the shrinking time will be reduced.
