What are the reasons for the yellowing of PET Self Wrap Braided Sleeve?

First of all, there are many reasons for yellowing: manufacturers will also produce yellowing during the production process, such as PET Self wrap braided sleeve, most of which will turn yellow during use; in addition, the yellowing of the silicone rubber aeration tube diaphragm is mostly caused by Improper operation in the production process causes yellowing, and different causes of yellowing need to be improved by different methods.

The product turns yellow quickly during use: Reasons The yellowing of PET Self Wrap Braided Sleeve usually occurs in dry, unventilated, airtight, high temperature, outdoors, direct ultraviolet radiation or chemical reaction environments, but in normal environments, yellowing The speed is relatively slow and can be used for 1~5 years, so it can be determined whether the product is used in these environments first.
1. In a dry, unventilated and closed environment, the yellowing of the Pet Self Wrap Braided Sleeve should be improved in the storage and use environment. The storage environment of Cable Sleeve should be ventilated and cooled. Under certain conditions, the temperature in the warehouse can be kept at room temperature. The environment can be properly watered to maintain humidity, or an electric fan can be used to cool down to keep the humidity of the Cable Sleeve relatively stable. The yellowing of the Cable Sleeve indicates that the Cable Sleeve is in the process of high-speed loss, which needs to be paid attention to. There are also some PET Self Wrap Braided Sleeve that need to be assembled in a sealed environment. For example, when used in a sealed environment, some products will inevitably turn yellow during assembly. materials or accessories. Adding anti-yellowing agents during the production process can greatly reduce yellowing.
2. Yellowing at outdoor high temperature: common cause: it is the limit value of the performance of the product when it comes into contact with the Cable Sleeve. Excessive operation of the Cable Sleeve is an important reason for accelerating the yellowing of the Cable Sleeve. The improved method can not only control the cost, but also reduce the yellowing speed of the Cable Sleeve. In order to completely solve the problem of yellowing caused by high temperature, high temperature Cable Sleeve can be directly used instead.
In addition, the outdoor yellowing is due to the fact that the PET Self Wrap Braided Sleeve is directly exposed to sunlight through wind and rain, and aging is accelerated due to physical factors. Secondly, the drop in outdoor temperature is also one of the influencing factors. It is recommended to avoid long-term outdoor use. If you really want to use it, you can choose bright colors such as black and yellow to delay the yellowing speed or hide the yellowing color.
3. Product yellowing caused by chemical reaction or slightly corrosive environment: If the PET Self Wrap Braided Sleeve needs to contact some slightly corrosive liquids or some chemical contacts, the Cable Sleeve will also turn yellow and melt violently, which means that the Cable Sleeve Can not contact strong acid and alkali. The improved method can use new Cable Sleeve material (fluorosilicon) for acid-base treatment (higher cost), which solves the acid-base problem and naturally solves the problem of Cable Sleeve yellowing.
4. Another reason that affects the yellowing of PET Self Wrap Braided Sleeve is the problem at the production end. The storage and use environment of many customers is suitable for the braided network management environment, but the yellowing speed of the product is relatively fast, indicating that there is a problem with the product itself.
