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.
high quality, easy to use general purpose heat shrink tubing made from flexible, flame retardant Polyolefin. 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 to a third of its original diameter and is ideal for covering irregular or awkward shapes
