Can the Automotive Wiring Harness Protection Sleeve turn white and be used again?

This is a question often raised by customers. Today, the editor will analyze whether the Automotive Wiring Harness Protection Sleeve can still be used after it turns white.

First of all, we need to know the composition of the Automotive Wiring Harness Protection Sleeve before we can know why the Automotive Wiring Harness Protection Sleeve turns white. The Automotive Wiring Harness Protection Sleeve is a latex liquid extracted from the Hevea clover tree. The excess water is extracted through the production process, and then shaped into a tube through a mold.
Frosting and whitening of Automotive Wiring Harness Protection Sleeve refers to the phenomenon that the compounding agent in the Cable Sleeve migrates from the inside to the surface. The main reason is that some compounding agents form a supersaturated state or incompatibility in the Cable Sleeve. Secondly, for the soluble compounding agents in the Cable Sleeve, after reaching the supersaturated state, the compounding agents close to the surface layer will be sprayed out of the surface first, because the closer to the surface layer, the lower the concentration of these compounding agents. Therefore, when the storage or use environment of the tube is too humid, part of the protease will be precipitated, and a layer of white powder will appear on the surface of the tube.
So is there any good way to reduce the whitening of spray cream? In fact, the whitening of the protective sleeve of the automobile wiring harness can be overcome by some simple processes. The silicone rubber product factory has done a good job in this regard. Not only will the tube not turn white, but it also eliminates the concerns of customers. Silicone rubber technicians suggest that if you want to reduce the whitening of the Automotive Wiring Harness Protection Sleeve, you should choose raw rubber with high solubility, or try to use raw rubber with similar solubility parameters to the compounding agent. In the production process of the Automotive Wiring Harness Protection Sleeve, the amount of solvent used should be reduced as much as possible. When the product is fully formed, it can be wiped with a relatively concentrated silicone oil, and then secondary vulcanization can reduce the occurrence of frosting.
Finally, when white powder appears on the surface of the tube, it can be wiped dry with a damp cloth and used without affecting the performance of the tube. Because what really affects the performance of the pipe is the aging of the pipe due to the pH or high temperature.
