What are the reasons for the yellowing of the Automotive Wiring Harness Protection Sleeve?

Automotive Wiring Harness Protection Sleeve, also called silicone tube, can also be named according to its use. For example, it can be called industrial Automotive Wiring Harness Protection Sleeve if it is used in industry, and it can be called food Automotive Wiring Harness Protection Sleeve if it is used for food. The common ones are transparent, medical, high temperature resistant, acid and alkali resistant Automotive Wiring Harness Protection Sleeve.

The Automotive Wiring Harness Protection Sleeve is used as a carrier for liquid, gas and other materials to circulate and cover. It is mainly made by adding the raw rubber of the Cable Sleeve to the double-roller rubber mixing machine or the closed kneader, and gradually adding white carbon black and other additives for repeated refining. According to the technical standards of the industry, it is extruded into a product. The process is more complicated. During production, a small mistake may cause quality problems of the tube, which may cause the tube to turn yellow easily in the later stage.
The reasons for the yellowing of the Automotive Wiring Harness Protection Sleeve are generally as follows:
1. The quality of double 24 is not good: you can replace it with better quality to solve this problem.
2. The amount of double 24 added is too large: reduce the amount of double 24 to an appropriate amount
3. Poor anti-yellowing property of Cable Sleeve: replace with better anti-yellowing Cable Sleeve
4. After the second-stage vulcanization: improve the ventilation conditions of the second-stage vulcanization
5. The rubber hose without secondary vulcanization should be stored in an airtight container.
