Will the Automotive Wiring Harness Protection Sleeve turn yellow when it is stored in a sealed bag after use?

Recently, some customers asked: "The Automotive Wiring Harness Protection Sleeve turns yellow and discolored after being used for a period of time." I don't know if the yellowed product will affect the later use, and if it is stored in a sealed bag after use, will it still turn yellow? Cable Sleeve manufacturers share: In fact, whether the protective sleeve of the Automotive Wiring Harness Protection Sleeve will turn yellow mainly depends on the quality of the raw material of the Cable Sleeve, the processing technology and the composition of the vulcanizing agent.

First of all, when the transparent Automotive Wiring Harness Protection Sleeve is formed, if the temperature of the forming mold is too high and the vulcanization time is too long, the color of the transparent Automotive Wiring Harness Protection Sleeve will turn yellow after molding. Secondly, if the anti-yellowing ability of the raw material of the Cable Sleeve is too poor, even if an anti-yellowing vulcanizing agent is added to the rubber compound, the finished product will still be yellow after molding, so it is recommended to replace the raw material of the Cable Sleeve with poor yellowing resistance.
In short, although the Automotive Wiring Harness Protection Sleeve has excellent weather resistance and aging resistance. But sometimes the Automotive Wiring Harness Protection Sleeve turns yellow. In order to avoid this situation as much as possible, you can choose a better vulcanizing agent according to actual needs, and according to the anti-yellowing requirements of the Automotive Wiring Harness Protection Sleeve, increase the anti-yellowing agent to prevent or inhibit the speed of yellowing; in terms of technology, the temperature of the mold and the vulcanization time of the product must be strictly controlled; in terms of raw materials, attention should be paid to the anti-yellowing properties of the raw materials of the Cable Sleeve itself. In addition, if the surface of the Automotive Wiring Harness Protection Sleeve is yellowed due to improper storage, it will not affect the later use.
