RS Pro Halogen Free Flexible Polyolefin Heat Shrink Tubing with 2:1 Shrink Ratio

From RS Pro a range of high quality, easy to use heat shrink tubing made from flexible, halogen-free flame retardant Polyolefin. The shrink ratio of this heat shrink tubing is 2:1 which means it shrinks to half of its original diameter. This heat shrink is halogen-free or zero halogen which means, when it overheats or burns, it produces less smoke and fewer toxic gasses making it ideal for use in environments where safety is an important consideration, especially if there is a risk of fire or electrical circuits overheating.

What is Heat Shrink Tubing?

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 protect and insulate the connection. 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. Larger shrink ratios are required to cover materials with a greater size variation.

Features and Benefits of Flexible Polyolefin Heat Shrink Tubing

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 to half its original diameter hence the ratio of 2:1. This flexible Polyolefin tubing has the following properties:

• Very flexible
• 2:1 shrinkage ratio, shrinks to half its original diameter
• Halogen-free with reduced acid gas emission and smoke generation
• Excellent flame retardancy
• Operating temperature range of -55 to +105°C
• Shrink temperature of 115°C minimum
• Excellent electrical insulation properties
• Resistant to common fluids and solvents

What is Polyolefin Heat Shrink Tubing Used For?

This polyolefin halogen-free heat shrink is very versatile and is used in both commercial and industrial applications. The halogen-free material means it is ideal for use in smoke sensitive areas such as public buildings, underground systems, hospitals, airports and submarines. Heat shrink tubing is used for protecting and sealing cable joints and in-line components such as disconnect terminals and wire splices. It can also be used to carry out repairs on existing worn or torn cable or wiring insulation. Applications include the following:

• Electrical insulation and protection of resistors and capacitors
• 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

How to use Heat Shrink Tubing

The diameter of the wire or cable is measured and the correct sized heat shrink tubing selected. A piece of the tube 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 piece of heat shrink shrinkable tube is moved over the joint and heated with a heat gun until it shrinks and forms a tight wrapping around the joint.
