What makes flexible waterproof casing act as a seal?
 
Flexible waterproof casing is a common sealing material, which has good sealing performance and can be widely used in various fields. So, what makes the flexible waterproof casing play a sealing role?
 
First of all, flexible waterproof casing adopts a special structural design, which is the basis of its sealing performance. Usually, flexible waterproof casing consists of three parts: inner sleeve, outer sleeve and intermediate filling layer. The material of the inner sleeve and jacket is usually highly elastic rubber or plastic material, and the filling layer is polymer material or other sealing materials. This structure design can make the flexible waterproof casing in the use of the process is not easy to deformation, thus ensuring its sealing performance.
 
Second, flexible waterproof casing has good corrosion resistance. Various chemical substances are often present in the modern industrial environment, and these substances can cause damage to the sealing materials and reduce their sealing performance. However, the polymer materials and other sealing materials used in flexible waterproof casing can effectively resist the corrosion of various chemical substances, thus ensuring its sealing performance.
 
In addition, flexible waterproof casing also has good resistance to high temperature and low temperature. In high or low temperature environments, many sealing materials will be deformed, rupture, etc., thus affecting its sealing performance. However, the polymer materials and other sealing materials used in flexible waterproof casing can effectively adapt to various temperature environments, thus ensuring its sealing performance.
 
Finally, flexible waterproof casing also has good waterproof performance. In various environments, such as water, wet environment, rainwater, etc., flexible waterproof casing can effectively prevent water penetration and ensure the safe operation of equipment. In short, flexible waterproof casing can be widely used in many fields, including electric power, communication, construction and so on. Its excellent sealing performance is mainly due to its special structural design, good corrosion resistance, high temperature resistance and low temperature resistance, as well as good waterproof performance. Therefore, when choosing sealing materials, flexible waterproof casing is a good choice.
