What are the reasons for accelerating the aging of Automotive Wiring Harness Protection Sleeve

Although the various performances of the Automotive Wiring Harness Protection Sleeve are relatively good, it will gradually age after long-term use, which is a normal phenomenon. If we use it normally in a normal environment, the aging speed of the Automotive Wiring Harness Protection Sleeve will be slower, but if it is not used properly, it will accelerate the aging of the Automotive Wiring Harness Protection Sleeve. So how do we avoid the aging of the Automotive Wiring Harness Protection Sleeve? Here are three reasons from cable gland finishing. I hope to be helpful.

1. The car wire harness protector is ozone resistant. However, the chemical activity of ozone itself is high and destructive, and it will also break the molecular chains in the Cable Sleeve. When the automotive wire harness protective sleeve used for deformation is mainly unsaturated rubber, cracks appear in the same direction as the Automotive Wiring Harness Protection Sleeve, which is the so-called "ozone cracking"; only an oxide film is formed on the surface without cracking. This is because the effect of ozone on the automotive wire harness protective cover varies depending on whether the Automotive Wiring Harness Protection Sleeve is deformed or not.
2. Moisture will have a great impact on the Automotive Wiring Harness Protection Sleeve. Although most of the Automotive Wiring Harness Protection Sleeve are used to guide water and air, when the Automotive Wiring Harness Protection Sleeve are soaked in water in a humid environment, they are prone to aging. This is because the water-soluble substances in the Automotive Wiring Harness Protection Sleeve are dissolved by water, Caused by factors such as hydrolysis or absorption. Especially under the alternation of water and oxygen, the Automotive Wiring Harness Protection Sleeve will age faster.
3. The last point is oxygen, which is different from ozone, but it is unavoidable in life. Oxygen will undergo free radical chain reaction with cable sleeve molecules in the cable sleeve, which will cause excessive crosslinking of the molecular chains and cause breakage, changing the performance of the cable sleeve. Oxidation is one of the important reasons for rubber aging.
The above are the main aspects, and there are many small problems that will also affect the service life of the Automotive Wiring Harness Protection Sleeve. Therefore, while paying attention to the big aspects, the small details cannot be ignored.
