Under what circumstances will the PET Velcro Braided Sleeve be deformed?

Because of its low price, simple manufacture, reliable function, and simple installation requirements, Cable Sleeve are widely used and also used in various Cable Sleeve. However, some inappropriate reasons during use will also make the Pet Velcro Braided Sleeve permanently deformed.

First of all, the compression and stretch coefficients of PET Velcro Braided Sleeve: due to the different formulations of Cable Sleeve compounds, the compression and stretch of Cable Sleeve produced by different companies are also different. Under long-term compression conditions, the product will have the appearance of stress relaxation. This phenomenon will gradually expand over time. The longer the time, the smaller the compression and tension, and the product will not be elastic enough, causing leakage. The direct change method is to increase the cross-sectional size of the product, but it will also lead to an increase in production and product mix.
Secondly, the relationship between the temperature of the PET Velcro Braided Sleeve and the relaxation process: temperature is very important to the relaxation of the Cable Sleeve. No matter which rubber material is used, the aging rate will be accelerated at high temperature. The higher the ambient temperature, the greater the deformation of the gas compressor. When the product is deformed by more than 40%, the elasticity of the Cable Sleeve will slowly disappear, resulting in leakage.
Also, there is initial stress when installing the PET Velcro Braided Sleeve. The long relaxation and gradual cooling of the sleep cycle will gradually wear off. In some cases, it may disappear with a sharp drop in temperature. Even if the rubber material is cold-resistant, the stress at 20 degrees is smaller than the stress at 20 degrees. When installing the PET Velcro Braided Sleeve, the initial stress should be set, fully considering the temperature coefficient in the working environment.
Finally, the effect of medium working pressure on the deformation of PET Velcro Braided Sleeve: Compared with the above two factors, medium pressure has a greater influence on the deformation of PET Velcro Braided Sleeve. Under all working conditions, it will cause deformation of the PET Velcro Braided Sleeve. With the development of modern hydraulic design, the pressure of hydraulic medium is constantly increasing. Cable Sleeve can work in such a high-voltage environment for a long time. The long-term deformation of the Cable Sleeve is irreversible, so different materials should be selected according to different working pressures, and rubber materials with relative pressure resistance should be selected. Correspondingly, in order to cope with the higher operating pressure, the degree of hardening of the pressure-resistant material Cable Sleeve will increase.
