Heat shrink tubing is named because it is a material that shrinks when exposed to heat. The heat shrinkable tube shrinks when heated. Many people wonder how high the temperature needs to be to shrink the heat shrinkable tube?

General ordinary heat shrinkable tube does not need high temperature. Normal shrinkage temperature 80-120℃. However, our Suzhou Feibo  often has customers asking questions about the temperature resistance of heat shrinkable tubes. So what is high temperature heat shrinkable tube? The material of high temperature heat shrinkable tube will be different from that of ordinary heat shrinkable tube. For example, Teflon heat-shrinkable tube, which belongs to the series of high-temperature heat-shrinkable tube, the shrinkage temperature of this tube needs 250 ℃ to complete.
Heat shrink tubing is a plastic material. There will be a certain temperature limit. If the temperature is too high, the heat shrinkable tube will melt, break, crack, etc. What is the temperature of the heat shrinkable tube?


The temperature resistance of the low-voltage Heat shrink tubing is up to 125℃;
The maximum temperature resistance of flexible PVDF Heat shrink tubing and diesel heat shrinkable tube is 150 ℃.
The maximum temperature resistance temperature of semi-rigid PVDF Heat shrink tubing is 175°C;
The temperature resistance of fluororubber heat shrinkable tube is up to 200℃;
, Teflon Heat shrink tubing has a maximum temperature resistance of 260 ℃.
The maximum temperature resistance of the above-mentioned Heat shrink tubing means that it can work for a long time. If the temperature exceeds the design temperature, the aging speed will shorten the service life, and the physical and chemical properties will be reduced. Therefore, when choosing a heat shrinkable tube, it is also necessary to choose according to the working temperature environment to achieve safe and reliable insulation protection. The maximum working temperature of various types of heat shrinkable tubes is for your reference, which is convenient to use when choosing heat shrinkable tubes. Among them, the maximum temperature resistance of the heat shrinkable tube is 260°C, which is also the highest among the heat shrinkable tubes.
