What is the reason for the aging of the Automotive Wiring Harness Protection Sleeve?

In the daily use of Automotive Wiring Harness Protection Sleeve, why the Automotive Wiring Harness Protection Sleeve will age? What is the reason for the aging of the Automotive Wiring Harness Protection Sleeve?

The aging of Automotive Wiring Harness Protection Sleeve generally occurs during the processing, storage and use of polymer materials. Due to various reasons, the established performance gradually changes or disappears and is scrapped.
Generally speaking, the main reasons for the aging of Automotive Wiring Harness Protection Sleeve are:
1. External reasons: mainly oxygen, oxides, ozone, heat, light, radiation, mechanical fatigue, and lack of processing.
2. Internal reasons: First of all, there are factors such as the type of Cable Sleeve, the molding method, the degree of bonding, the type of cooperative drug, and the processing engineering of the Automotive Wiring Harness Protection Sleeve factory. Secondly, there are unsaturated factors in the internal molecular structure, and various groups such as hydroxyl groups are prone to new chemical reactions.
Oxidation is one aspect of knit sleeve aging. Oxygen has an aging effect on the Cable Sleeve molecules in the Braided Sleeve, and the molecular chains are cracked, resulting in a change in the function of the silicone. Secondly, the Cable Sleeve is also easily damaged when it is wet in the rain or soaked in water. Especially under the conditions of water immersion and air exposure, the aging of the Braided Sleeve will be accelerated.
