The long service life and aging degree of silicone products are all the flaws of silicone sealing rings. We know that generally all silicone products suitable for sealing have such a defect. Whether using silicone products, silicone rubber products, or other materials, they will gradually lose their initial performance after being subjected to the damage of their own environment and the test of time, As a result, the product itself cannot be achieved and its function cannot be demonstrated.

There are actually many reasons that affect the short service life of silicone sealing rings, but silicone rings in sealing are often affected by several common phenomena.

The force magnitude and compression durability of silicone sealing rings can directly or indirectly affect the service life of silicone seals. They are influenced by the shape of the main body itself, as well as the installation methods such as flat, concave and convex grooves or grooves. Different installation methods of each product may lead to uneven force distribution and force center displacement, resulting in a situation where one side is heavy while the other is light, In such a long-term accumulation of uneven stress, it is easy to cause permanent compression deformation. When the silicone sealing ring is removed again, deformation may have already occurred. Therefore, during installation, it is necessary to control the balance and the degree of force evenly and comprehensively.

Sometimes product size errors can lead to gaps and deformation.

The gap problem can be divided into several factors. Firstly, there is a problem with the rubber material of the material. Many silicone materials may have poor rebound force and insufficient tensile force due to formula reasons, resulting in gaps and leakage during use due to insufficient force. Secondly, there are problems with the processing of silicone products by manufacturers: products that are brittle, resulting in thinner rolled edges of silicone products, are prone to this problem. If they are softened, the rubber material may have internal bulging and lack of maturity, leading to deformation and gap problems after long-term tension and compression.

The influence of softness and hardness can often change the functionality and structure of silicone rubber products due to differences in softness. Therefore, during the use of silicone sealing rings, due to the selection of different softness and hardness, when subjected to force, tension, compression and other phenomena, silicone sealing rings will inevitably encounter problems such as gaps, excessive force, high hardness, and difficulty in product deformation and rebound.

So the service life of silicone sealing rings can only be determined through various inspection methods. However, we know what causes the service life of silicone sealing rings to become shorter, so we can be as cautious as possible to improve the service life of silicone sealing rings.
