Heat shrinkable tubing has excellent insulation properties and excellent service life, so it is widely used in the electronic and electrical industry, mainly for insulation protection of wire harnesses. But what is the maximum temperature that heat shrinkable tubes can withstand? This mainly depends on the material and production process of the heat shrink tube.

    According to the different models of heat shrinkable tubes, the working temperature is also different. Below, I will directly give you the maximum temperature resistance of heat shrinkable tubes made of various materials. You can correspond one by one in the subsequent product selection, which is very convenient.

1. Low-voltage insulating heat shrinkable tubes can withstand temperatures up to 125°C;

2. Double-wall heat-shrinkable tubes, medium-wall heat-shrinkable tubes, and thick-wall heat-shrinkable tubes can withstand temperatures up to 125°C;

3. Military standard heat shrink tubing and military standard double-wall heat shrink tubing can withstand temperatures up to 135°C;

4. Soft PVDF heat shrink tubing and diesel-resistant heat shrink tubing can withstand temperatures up to 150°C;

5. Semi-rigid PVDF heat shrinkable tube has a temperature resistance of up to 175°C;

6. Fluorine rubber heat shrinkable tube has a temperature resistance of up to 200°C;

7. Teflon heat shrink tubing can withstand temperatures up to 260°C.

    The maximum temperature resistance of the heat shrinkable tube mentioned above means that it can continue to work for a long time. If the design temperature is exceeded, the aging rate may be accelerated, the service life will be shortened, and the physical and chemical properties will also be reduced. Therefore, when choosing heat shrinkable tubes, you also need 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 will come in handy when choosing heat shrinkable tubes. Among them, Teflon heat shrinkable tubes have a maximum temperature resistance of up to 260°C, which is also the highest temperature resistance among heat shrinkable tubes.
