Applications

The polyolefin material used in our tubing offers superior electronic insulation and mechanical protection. With its high shrinkage ratios, this heat shrink tubing is ideal for connecting a wide range of wire bundles or components.
Its thick wall design is especially suitable for electronic insulation and mechanical protection of medium and high-voltage power cables. The inner layer's hot-melt adhesive provides waterproof sealing for connected components.

Features

High shrinkage ratio, accommodating larger diameters
Black outer layer with high UV resistance
Semi-rigid polyolefin material for superior electronic insulation and mechanical protection
Lowest full shrink temperature: 135°C
