What causes the service life of silicone sealing rings to decrease?

The aging lifespan ability is the hardness of silicone rubber rings. All silicone products suitable for sealing have such a defect, such as certain defects in our common mechanical doors and windows, electronic product seals, and automotive waterproof sealing rings. Whether silicone, rubber, or other materials are used, they will gradually lose their functionality and fail to achieve practical results after being subjected to environmental damage and time, Unable to demonstrate the effectiveness of the product.

There are many main reasons that affect the service life, but in any sealing process, silicone rubber rings can be affected by several common phenomena. The magnitude of the force affects or compresses the permanent deformation. Different installation methods, such as flat surfaces, concave and convex grooves, or grooves, are used to install each product. The installation method of each product is different, which may lead to uneven force distribution and force center deviation, with one side being heavy and the other being light. After long-term accumulation of force, the compression permanent deformation is caused. When the sealing silicone ring is removed again, it is likely that it has already deformed, So during installation, it is necessary to control the balance and the degree of force evenly and comprehensively.

Incorrect product size leads to gap deformation: The gap problem can be divided into several factors. Firstly, due to the material's rubber material issue, many silicone materials have poor rebound force and insufficient tensile force due to formula reasons, resulting in small force during use and gaps leading to leakage. Processing problems with silicone ring processing manufacturers: For example, products that are brittle and have thinner edge thickness are prone to this problem. Softened products can cause internal bulging of the rubber material, resulting in deformation and gap problems after long-term tension and compression. The softening or embrittlement of a product can lead to functional failure, often not due to material and product structure issues, but rather due to the impact on the quality standards of the product during the production and processing process of silicone rubber product manufacturers. For example, during processing, the product's hardness and softness requirements are not understood, and the processing time is stretched, resulting in the product being too brittle. During the installation process, cracking occurs, or the product is softened in order to improve processing efficiency, Causing deformation of the product under stress.

The influence of hardness and softness can often completely change the functionality and structure of silicone rubber products based on their different softness. Therefore, during the use of silicone sealing rings, due to the selection of different hardness and softness under stress, stretching, extrusion, and other phenomena, some unavoidable problems may occur in the sealing ring, such as extrusion gaps, excessive force, high hardness, and no rebound of product deformation
