What Shorten the Life of the Silicone Connector Seal?

Silica gel is more and more popular because of its environmental performance, such as silicone seal. What shorten the life of the Silicone Connector Seal?

Silicone Connector Seal

There are many main reasons that affect the service life, but any sealing silicone grommet will be affected by several common phenomena.

• 
  

  Uneven force causes permanent deformation

  
  

There are different ways to install silicone connector seal on a flat surface, a concave-convex groove or a groove. The different installation methods of each product are likely to cause uneven force and a shift in the center of gravity of the force, with one side heavy and the other light. After a long period of stress, it will cause permanent deformation. When the sealing silicone ring is removed again, it may have been deformed, causing silicone seal to be unusable. Therefore, it is necessary to control the uniform force during installation.

  Softness factor

  
  

In many cases, the functionality and structure of the product can be completely changed according to the different softness of the silicone product. Therefore, after the silicone sealing ring is stressed, stretched and squeezed during use, some unavoidable problems will occur in the sealing grommet. Such as extrusion gap, product deformation without springback and other issues.

  Gaps and gap deformation

  
  

The gap problem can be divided into several factors. One is the issue of materials. Many silicone materials have poor elasticity due to the formulation, and insufficient stretching force results in low force during use, resulting in gaps and sealing leakage. The second is the problem of the silicone ring manufacturer's own products. There are gaps in the deformation after long-term tension and compression.
