RS PRO Adhesive Lined Heat Shrink Tube, Blue 6.4mm Sleeve Dia. x 1.2m Length 3:1 Ratio

From RS Pro a range of high quality, easy to use adhesive lined or dual wall heat-shrink tubing made from flexible, flame retardant Polyolefin. This heat shrinkable tubing has a high shrink ratio of 3:1 which means it shrinks to a third of its original diameter and is ideal for covering irregular or awkward shapes. The adhesive lining of this tubing, when melted, provides a watertight sealing and encapsulates wire joints.

Heat shrink tubing is a type of extruded plastic tubing that can be cut to size and fitted over a wire or cable joint to provide protection and insulation. When heated is applied the tubing shrinks permanently providing a protective seal. The amount it shrinks depends on its shrink ratio. When you buy the tubing it is in its expanded state, this expanded tubing has memory so when it is heated it returns to its original state

The diameter of the wire or cable is measured and the correct sized heat shrink tubing selected. A piece tubing is cut to size which is long enough to cover the connection or joint after heating. This then slides onto the wire. After the cable or wire has been joined the heat shrink tubing is moved over the joint and heated with a heat gun until it forms a tight wrapping around the joint

Flexible Polyolefin is a material derived from polyethylene and is one of the most commonly used insulating materials being both highly flexible, fast shrinking and durable. When heated this polyolefin tubing shrinks radially a third of its original diameter hence the ratio of 3:1. This tube has an inner adhesive lining, which, when heated, melts to form a watertight sealing around the joint. This type of heat shrink is also called dual wall heat shrink.

• Very flexible
• Adhesive lined for waterproof sealing
• Flame retardant
• Good adhesion to metals, polyolefin and PVC
• 3:1 shrink ratio, ideal for irregular shapes
• Operating temperature range of -55 to +110°C
• 110°C shrink temperature

• Excellent abrasion resistance

This polyolefin adhesive lined heat shrink is very versatile and is used in both commercial and industrial applications. The meltable adhesive liner provides waterproof sealing and encapsulation for cable joints, wire branches and in-line components such as disconnect terminals and wire splices. This adhesive tubing is also ideal for encapsulating electronic devices that have irregular shapes or profiles. Applications include the following:

• Waterproof sealing and encapsulation of wire joints
• Electrical insulation
• Environmental protection against moisture, dust and chemicals.
• Mechanical protection to wires and small parts from abrasion
• Mechanical strain relief on cable and connector joints to prevent damage caused by flexing or bending
• Bundling and organizing harness wires, cable and tubing
• Colour coded identification of cables, wires and components
