What factors will affect the service life of silicone seals?

March 22, 2022


      How many years can the silicone sealing ring be used? This is determined by the service life of the silicone sealing ring. There are many factors that affect its service life, but the silicone ring in the sealing is often affected by several common phenomena.

 

 

     First of all, the force and compressibility of the silicone sealing ring can directly or indirectly affect the service life of the silicone sealing ring. The different installation methods of the sealing rings may lead to uneven stress and shift of the center of force, resulting in a situation where one side is heavy and the other is light. Under such a long-term uneven backlog, it is easy to cause compressive deformation. When the silicone sealing ring is removed again, it is likely that the phenomenon of deformation has occurred, so it is necessary to control the balance and the degree of force to be evenly integrated during installation.

 

       Secondly, there is an error in the size of the silicone sealing ring, which leads to a gap and deformation. The gap problem can be divided into several factors: First, the problem of the material of the material. Many silicone materials may have poor resilience and insufficient tensile force due to the formula. Leakage occurs due to gaps. Second, there are problems in the processing of silicone products processing manufacturers: the products are brittle, which leads to the problem of thin silicone sealing rings. There is a gap problem in the deformation after pressing.

 

      Finally, the influence of softness and hardness. In many cases, the softness of the silicone sealing ring can change the function and structure of the product. Therefore, due to the choice of different softness and hardness during the use of the silicone sealing ring, it will be subjected to stress and tension. When stretching, squeezing and other phenomena, the silicone sealing ring will have an unavoidable problem, such as gaps, excessive force, too high hardness, product deformation is not easy to rebound and so on.

 

    So, how many years can the silicone sealing ring be used? It can only be known through a variety of inspection methods, but we know what causes the service life of the silicone sealing ring to be shortened, so we can take precautions as much as possible, thereby improving the service life of the silicone sealing ring.
