Pay attention to these three aspects and maintain your silicone sealing ring well

Silicone sealing ring, during long-term adhesion and metal compression, often experiences non rebound and non stress due to frequent stress. How to maintain and use silicone sealing ring for a long time.

Some sealing rings have been used in harsh environments for a long time, such as aging under the action of oxygen, heat, and light, leading to deformation. Therefore, in the initial stage, the use environment and time of silicone sealing rings need to consider the material and whether the product can maintain long-term life, and the elasticity is not affected. Generally, from these three aspects

The temperature of the environment around the silicone sealing ring

During use, various high and low temperatures are a major factor affecting the product. Although silicone materials can withstand high temperatures ranging from over 200 degrees to -40 degrees, their long-term suitability for harsh heat conditions will accelerate the aging of silicone sealing rings. The higher the temperature, the greater the deformation of the product. The maximum stress deformation of silicone materials is generally over 40%, which will completely lose its working performance, leading to sealing leakage and other reasons. When used at low temperatures, it is recommended to increase the compression and tensile strength appropriately. When used at low temperatures, attention should be paid to the phenomenon of product necrosis and deformation rupture.

Tensile strength of silicone sealing ring

Tensile strength is one of the main operating capabilities of silicone sealing rings, so when producing silicone products, manufacturers choose corresponding tensile strength materials and various hardness usage conditions. Therefore, for long-term repeated use needs, high tensile silicone materials can be selected for processing and production to prevent the product from affecting its performance over time, Due to the long-term operation of silicone rubber in situations beyond the tension range, it often causes the product to become loose and lose tension. Therefore, under sufficient conditions, reducing the working intervention tension is the biggest factor affecting the deformation of silicone material during long-term use. Therefore, reducing the working pressure is the best way to maintain the sealing ring.

Selection of raw materials for silicone sealing rings

In addition, high-quality materials are used for product performance. The higher the tensile strength and hardness performance, the better the product quality.
