Filed under heat shrinkable tubing

Heat shrink tubing is used to insulate wires for wire conductors, joints, connections and terminals of any electrical work. Their main purpose is to protect cables against abrasives and other environmental factors.

Apart from protection, heat shrink tubing is also used to join wires together, create seals for cable entry and repair insulation. Heat shrink tubing are more reliable and long lasting, thus preferred in multiple industries. Here are a few basics!

Types and manufacturing material of heat shrink tubing

The shrinking quality of these tubes is because of their manufacturing material. These are made from thermoplastics, including polyolefin and fluoropolymer. Different material may be chosen for different applications.

1.      Fluoropolymer tubing

All About Heat Shrink TubingThese can be FEP, PFA, PVDF or heat shrink PTFE tubing.

Polytetrafluoroethylene (PTFE) heat shrink tubes have a wide temperature range, from -55 °C to 175 °C. With a low coefficient of friction and high resistance to both chemicals and punctures, PTFE tubes are widely used in industry.

Fluorinated ethylene propylene (FEP) tubes provide a low-cost alternative to PTFE. FEP is an electrical conductor, inert to most solvents and chemicals. It is also highly resistant to extreme cold, heat and ultraviolet (UV) radiations. Hence, it is an excellent choice for most applications.

Manufactured from Polyvinylidene Fluoride (PVDF), Kynar heat shrink tubes have excellent cut-through resistance and protection against abrasions. PVDF tubes are specially made for high temperature applications.

2.     Polyolefin tubing

Polyolefin heat shrink tubing are the most commonly used because of their ease of use and low cost. From railway and automotive to aerospace and military, these tubes are used for a wide range of applications.

These are flexible and fast shrinking tubes, available in a variety of colors. This is why they’re often used for color coding, replacing the use of adhesive tapes. Flame retardant options are also available.

Why are heat shrink tubes used most often?

Irrespective of the material used for manufacturing these tubes, heat shrink tubing are durable and long lasting. These tubes seal excellently as they conform to the shape of cables upon heating. Since these tubes come in a number of colors, they also have an aesthetic appeal. Colored tubing helps organize the wires.

Overall, these tubes make the assembly of electrical devices and machines faster and a lot easier. It also saves you both time and resources by preventing future obstructions. These tubing reduce electricity related risks and protect the electric devices and equipment in industrial settings.
