Heat shrink tubings are thermoplastic components used mainly by electricians and engineers as insulations to protect against environmental factors like moisture, dust, and chemical contamination.

When heated, the heat shrink tubing decreases in size, creating a firm and tight cover over the component being insulated, for example, electrical wires. This makes it ideal for covering various substrate materials conveniently.  

PTFE Heat Shrink Tubing Explained

PTFE (Polytetrafluoroethylene) is a synthetic compound popular for low friction coefficient and optimum chemical resistance. PTFE is operational in a considerable range of temperatures as compared to other polymers. This wide range of temperatures makes its usage applicable in extreme cold and hot conditions. 

PTFE heat shrink tubes are non-inflammable, non-toxic, and highly resistant to UV radiation, making them ideal for both indoor and outdoor applications.

Benefits of PTFE Heat Shrink Tubing

Heat shrink tubing options provide an excellent protective covering. Their inherent properties help them withstand cuts, scuffs, abrasions, and minimum impact circumstances. This makes these tubings ideal for different conductors and CES (cable entry seals).

Heat shrink tubing solutions get made from materials like PTFE and PVC. PTFE supports a use temperature of up to 500ºF. Therefore, consider using PTFE heat shrink tubing if your organization deals with substrates that handle high temperatures.

Besides, you can use heat shrink tubes to identify specific components through color-coding, especially in electrical systems. For example, a red tubing often indicates a specific wire has a live current.  

Moreover, PTFE heat shrink tubing options have outstanding electrical and thermal insulation properties. Therefore, they are the best option if you work with electrical wire conductors, terminals, and joints. They help to prevent accidents associated with making contact with current-conducting wires or hot surfaces.

Essential Factors to Consider When Choosing PTFE Heat Shrink Tubing

Before choosing a convenient heat shrink tubing option, you need to consider various factors other than the type of material. Of course, PTFE is arguably the best material, but what else should you look for?

First, the shape of the product that you need to cover should influence your decision. That also means considering the heat shrink ratio. Most linear components like mandrels require lesser ratios as compared to ones with irregular shapes.

Apart from the heat shrink ratio, you also need to pay attention to the product's dimensions. Ensure the tubing you pick will cover the component in question without losing alignment.

If your applications need extra toughness and high strain relief limits, go for stiff tubing with relatively thicker walls. Any other applications can work well with thin-walled heat shrinking tubings with minimum rigidity.

Finally, if you deal with applications that require proper insulation, like in electrical and wiring setups, ensure the heat shrink tubing solution you settle for has optimum insulating capabilities by creating complete covering over the wires.
