A high quality, easy to use general purpose heat shrink tubing made from flexible, flame retardant Polyolefin. 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.
This heat shrinkable tubing has a low shrink temperature of just 70°C (minimum) and a high shrink ratio of 3:1 which means it shrinks from its original diameter of 9mm to a third of its size to 3mm. A perfect solution for covering irregular or awkward shapes

Polyolefin 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.

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

This polyolefin heat shrinkable tubing is very versatile and is used in both commercial and industrial applications for protecting and sealing cable joints and in-line components such as disconnect terminals and wire splices.
