Factors affecting silicone sealing products and solutions

The silicone sealing ring in silicone sealing products, which is subjected to long-term adhesion and metal compression, often experiences non rebound and non stress due to frequent stress. Some sealing rings have been used in harsh environments such as oxygen, heat, and light for a long time, leading to aging and phase transformation, So in the early stages, 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.

1. 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, long-term use in harsh heat conditions can 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 above 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.

2. 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, reducing the working intervention tension under sufficient conditions is the biggest factor affecting the deformation of silicone material during long-term use.

Therefore, reducing working pressure is the best way to maintain the sealing ring. In addition, high-quality materials are used in the performance of the product. The higher the tensile strength and hardness of the product, the better the product quality.
