Is heat shrinkable tubing resistant to high temperatures? First of all, let me tell you that heat shrink tubing is resistant to high temperatures. The continuous working temperature of heat shrinkable tubes ranges from 125°C to a maximum of 260°C, which mainly depends on the material and model of heat shrinkable tubes. Different materials and models of heat shrinkable tubes have different working temperatures, so it needs to be determined according to the product. Choose the corresponding type of heat shrinkable tube according to the working temperature environment. According to different materials, heat shrinkable tubes are mainly divided into PE ordinary heat shrinkable tubes, glued heat shrinkable tubes, military standard heat shrinkable tubes, PVDF heat shrinkable tubes, and fluorine rubber oil-resistant heat shrinkable tubes. , Teflon heat shrinkable tubes and other 6 categories. Let’s take a look at the working temperature and high temperature resistance of various types of heat shrinkable tubes. The high temperature resistance is from low to high:

1. PE ordinary heat shrink tube is the most widely used model. It is mainly used for binding wire harnesses and insulation in the electronic field. The maximum continuous working temperature can reach 125°C.

2. Glued heat shrinkable tubes can include double-walled heat-shrinkable tubes, medium-walled heat-shrinkable tubes, and thick-walled heat-shrinkable tubes. The difference between them is that they have different wall thicknesses. Their working temperatures are basically the same, and the rated working temperature is also 125°C.

3. Because military-grade heat-shrinkable tubes must meet the military standard requirements for high flame retardancy, the working temperature is slightly higher than ordinary heat-shrinkable tubes and can reach 135°C.

4. PVDF heat shrinkable tubes can be divided into soft and semi-hard types. PVDF heat shrinkable tubes can be made of medical grade. When placing an order, you need to inform the heat shrinkable tube manufacturer DUWAI in advance. The working temperature of the flexible PVDF heat shrinkable tube can reach up to 150℃, and the working temperature of the semi-rigid type can reach up to 175℃.

5. Fluorine rubber oil-resistant heat shrinkable tubing can not only withstand high temperatures, but can also continue to be undissolved in high-temperature oils. Its physical and chemical properties are very excellent, and its maximum temperature can reach 200°C.

6. Teflon heat shrink tubing is currently the most resistant to high temperatures in the heat shrink tubing industry. Its Teflon material is considered the king of plastics. Therefore, heat shrink tubing produced with Teflon is also a leader in the industry and can withstand high temperatures. For some acid and alkali solutions, the maximum continuous operating temperature can be stabilized at 260°C.

    Heat shrinkable tubes can withstand high temperatures, and you can choose the corresponding model according to your own needs. The compatibility and selectivity are very strong. Heat shrinkable tubes not only have excellent high temperature resistance, but also have good low temperature resistance. The most common ordinary heat shrinkable tubes can withstand low temperatures of minus 45℃ without cracking. Teflon heat shrinkable tubes can withstand low temperatures of minus 65℃. No cracking.
