Analysis of the life time of Automotive Wiring Harness Protection Sleeve at extreme temperature

Generally, when customers inquire about Automotive Wiring Harness Protection Sleeve, they will ask: "Is your Automotive Wiring Harness Protection Sleeve resistant to high temperature or low temperature?" In fact, ordinary Automotive Wiring Harness Protection Sleeve are not resistant to high temperature and low temperature, only specially made Automotive Wiring Harness Protection Sleeve are resistant to high temperature and low temperature. Is it possible that the high temperature resistant Automotive Wiring Harness Protection Sleeve can always work in a high temperature environment (above 200°C)? And the low temperature resistant Automotive Wiring Harness Protection Sleeve can always work in low temperature (below -20°C)?

The answer is definitely not. For example, the human safety voltage is 36V. In a short period of time, 36V voltage will not harm the human body. It is also possible to get an electric shock if exposed to 24V voltage for a long time. 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 the limit temperature of the Automotive Wiring Harness Protection Sleeve is -70 to 300 °C.
However, some customers may misunderstand that it can work at a temperature of -70°C to 300°C all the time. However, the editor suggests that it is best not to work in a high temperature environment above 200°C or a low temperature environment below -20°C for a long time, so as to prolong the service life of the Automotive Wiring Harness Protection Sleeve.
