== Buying Heat Shrink Tubes <ref name = "ref2" /> ==Heat shrink tubing comes is available in a wide range variety of colors and sizes. It also comes with a variety wide range of protection levels, including heavy wall, multiple wall, and single wall. <br \>Here are some things to parameters you should consider if you’re buying heat shrink tubing:* '''Maximum diameter of your cable bundle:''' This will help you choose the correctly-sized heat shrink right size of your tubing. Remember, your tubinghas to go over your wire before melting.* '''Temperature range of your environment :''' Some heat shrink Depending on this, you will choose tubing is rated to extremely having a high and low temperaturesoperational temperature range, while other tubing is designed for more moderate environmental conditionsor a lower range.* '''Wall thickness:''' Heat Typically, heat shrink tubing is typically categorized by heavy wall, multiple wall, and single wall tubes. Thicker walls have a higher cost and can thicken your cables, but provide enhanced improved durability, rigidity, and abrasion resistance – but come at an extra cost and can unnecessarily thicken your cable arrangementrigidity.* '''Required resistance properties:''' For example, If your wires may be exposed to oils or chemicals , you would require your tubing to have chemical and oilsoil resistance properties.

'''2:1 ratio:''' These tubes shrink to half its their original size when heat is applied <br \>'''3:1 ratio:''' These tubes shrink to one third of its their original size when heat is applied

They These tubes maintain high flexibility even at low temperatures and . They also meet stringent international specifications. Their operating temperature range is -75 to 150 °C, which is sufficiently wide. A common shrink ratio is 2:1.

It is a versatile electrical insulator and is inert to most chemicals and solvents. Additionally, it is highly very resistant to extreme levels of heat, cold, and ultraviolet radiation, thereby making it an excellent material for heat-shrink tubing applications.

The These, as mentioned above, are most commonly used heat shrinktubes and have maximum use for temperatures from -55 to 135 °C, and are used by the military, aerospace and railway industries. They are flexible and fast-shrinking, and manufactured in a wide range of colors (including clear), which can be used for color-coding wires. Polyolefin tubing shrinks at 143°C. Polyolefin heat-shrink tubing typically shrinks 2:1 diametrically, but there are high-grade polyolefin heat-shrink is tubes also available with a 3:1 ratio. Polyolefin Interestingly, polyolefin tubing may withstand survive being touched with a soldering iron.
