Analysis of Automotive Wiring Harness Protection Sleeve under high and low temperatures

When some customers ask about our Automotive Wiring Harness Protection Sleeve, they will ask whether your Automotive Wiring Harness Protection Sleeve are resistant to high temperatures (above 200°C) or whether they are resistant to low temperatures (below -20°C). Ordinary Automotive Wiring Harness Protection Sleeve are not resistant to high and low temperatures. Only specially made Automotive Wiring Harness Protection Sleeve are resistant to high and low temperatures. Can Braided Sleeve always work in high temperatures (above 200°C)? Can they withstand low temperatures?

Automotive Wiring Harness Protection Sleeve can work in high temperatures of 300°C or low temperatures of -70°C for a short period of time without affecting performance. However, if you work for a long time, it will inevitably destroy the molecular structure of the Automotive Wiring Harness Protection Sleeve and damage the Automotive Wiring Harness Protection Sleeve. This is why it is said that the ultimate temperature of Automotive Wiring Harness Protection Sleeve is -70 to 300°C.
The answer is definitely not. For example, the safe voltage for humans is 36V for a short period of time. 36V voltage is not harmful to the human body. It is also possible to get an electric shock if exposed to 24V voltage for a long time. The principle of Automotive Wiring Harness Protection Sleeve is the same.
Some customers may misunderstand that it can always work in temperatures from -70 to 300°C. However, the editor of Braided Sleeve recommends that the Automotive Wiring Harness Protection Sleeve should not work above 200°C for a long time when working at high temperatures, or not lower than -20°C for a long time when working at low temperatures.
