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

As modern Cable Sleeve are used more and more frequently, many investors have shifted their entrepreneurial direction to the investment in Automotive Wiring Harness Protection Sleeve. These entrepreneurs introduced advanced production equipment and talents, but when the products were rolled off the assembly line, they found that the Automotive Wiring Harness Protection Sleeve, which should have been transparent and colorless, was yellow, which seriously affected the appearance and use of the products. What are the factors that cause the color of the Cable Sleeve to turn yellow instead of transparent? In response to the questions of new investors, engineers who have been engaged in the research and development of Automotive Wiring Harness Protection Sleeve for many years explained the reasons.

1. Improper selection of vulcanizing agent
No matter what kind of Cable Sleeve is produced, the use of vulcanizing agent is very important. Now there are two types of common vulcanizing agent and anti-yellowing vulcanizing agent on the market. Although both of them can play a good role in the vulcanization of Cable Sleeve, their scope of application is still different. For example, the common type is generally used in Non-exposed Automotive Wiring Harness Protection Sleeve or products that do not have a high color for Cable Sleeve, while anti-yellowing vulcanizers are used in Automotive Wiring Harness Protection Sleeve that require higher transparent colors or require exposed installation. Therefore, when purchasing or adding vulcanizing agents, we must pay attention to its use occasions and color requirements.
2. In the production vulcanization process, the control of the process is not in place
The research and development personnel of the Automotive Wiring Harness Protection Sleeve said that if the temperature of the production mold is too high during the production process of the Cable Sleeve, or the vulcanization process takes too long, it may cause the transparent Cable Sleeve to turn yellow. Regarding this point, you may wish to experiment several times to find the most suitable temperature and time for the heating and vulcanization process, so as to reduce the chance of yellowing of the Cable Sleeve. In short, as long as these problems are strictly controlled in production, they can still be effectively avoided, so we must pay attention to them.
