Heat shrinkable tubing is a special heat shrinkable sleeve that can be heated to make its inner diameter smaller, hence the name heat shrinkable tubing. It has the function of high temperature shrinkage, soft and flame retardant, insulation and anti-corrosion. It is widely used in the insulation protection of various wire harnesses, solder joints and inductors, and in the rust and corrosion protection of metal tubes and rods.
When it comes to insulating sleeving, firstly it is a tube and secondly it has an insulating effect, with insulation, sealing and protection in order to be called insulating sleeving.
Insulation sleeving contains a wide range of types, including UNIPE, glass fibre tube, corrugated wave tube, PVC sleeving and of course heat shrinkable tube. Just remember that heat shrink tubing belongs to the insulating sleeving that can be heated and shrunk. The main role of heat-shrinkable tubing is insulation, sealing and protection, so heat-shrinkable tubing is also a kind of insulating casing, but heat-shrinkable tubing has the function of shrinking when heated.
In fact, the heat shrink tube has the effect of insulation is the default, when buying heat shrink tube also need to know its insulation level, generally conventional are 600V. insulation heat shrink tube is the most common commonly used heat shrink tube, it can effectively protect the metal tube, rod, so that it is not corrosive, rust, while the low-voltage wire and cable can also do the corresponding protection, but also to protect the construction personnel It also protects the personal safety of the construction worker, allowing him to work with confidence.
Insulation heat-shrinkable tube also has different colours, but that is only different colours, in terms of quality and other aspects of performance are the same, the price is also the same, but there is an exception, that is, two-coloured heat-shrinkable tube, of course, the quality is also the same, is its price is slightly higher than the other colours of heat-shrinkable tube, two-coloured heat-shrinkable tube is generally yellow and green colour, commonly used in ground or pipe marking.
If there is no gap between the insulating sleeve and the product to be covered or if the sealing effect is better, use heat shrinkable tubing, if it is convenient to add the wire harness later, use non-shrinkable sleeve. What is the difference between heat shrinkable tubing and insulating sleeving? The biggest difference is that the heat shrinkable tube can be heated shrinkage, while the general default of insulation casing is not shrinkage, I hope that these help you after the purchase of heat shrinkable tube and insulation casing.
