What are the standard specifications of the silicone seal ring, you will know after reading

Silicone sealing ring, as an indispensable sealing element in modern industry, with its excellent high temperature resistance, corrosion resistance, anti-aging and other characteristics, in machinery, automotive, electronics, food and other fields have been widely used. The formulation of its standard specifications is not only related to the performance of the product, but also directly affects the interchangeability and use effect of the product.

1. Size specifications
The size of the silicone sealing ring is the primary consideration in the selection and use process. In general, the size of the silicone sealing ring includes three main parameters: inner diameter, outer diameter and thickness. On the market, the internal diameter of common silicone seals ranges from 1mm to 1200mm, the outer diameter ranges from 2mm to 1500mm, and the thickness is between 0.5mm and 40mm. Different shapes of silicone seals, such as O-rings, U-rings and V-rings, their size specifications are also different. For example, the inner diameter and outer diameter of the O-ring can range from 1mm to 1200mm, and the thickness can range from 0.5mm to 12mm; The inner diameter and outer diameter of the U-ring can be from 2mm to 1200mm, and the thickness can be from 1mm to 20mm.
In addition, the size specifications of the silicone sealing ring are also subject to multiple constraints of international standards, industry standards and enterprise standards. For example, the Japanese standard, the American standard and other international standards have detailed provisions on the size of O-rings, such as ID1.801.90, ID2.801.90 and other specifications; Domestic enterprises may develop more detailed specifications according to their own needs. Therefore, when selecting the silicone sealing ring, it is necessary to select according to the specific application scenarios and needs, and refer to the relevant standards.

2. Material requirements
The material requirements of the silicone sealing ring are equally strict. According to the standard requirements, the silicone sealing ring should be made of silicone rubber material that meets the requirements, and the material should have the characteristics of high temperature resistance, corrosion resistance and aging resistance. At the same time, the physical and chemical properties of silica gel materials should also meet the requirements of use, such as tensile strength, tearing strength, hardness, resilience and so on. In addition, in order to ensure the safety and environmental protection of products, silicone materials also need to pass relevant testing and certification, such as FDA food grade certification, RoHS environmental protection directives.

3. Performance requirements
The performance requirements of silicone seals are also an important part of their standard specifications. According to the standard requirements, the silicone sealing ring should be able to withstand a certain pressure, temperature and chemical corrosion conditions, while having high wear resistance, fatigue resistance and mechanical strength. In harsh environments, silicone seals should be able to maintain good sealing performance and stability, not affected by rain, snow, humidity, ozone, solar ultraviolet and other external factors. In addition, the silicone sealing ring should also have good electrical insulation and flame retardant properties to ensure the safe operation of the equipment.

4. Production and testing
The production process of silicone seals also follows strict standards and processes. From raw material preparation to formulation, rubber calendering, molding, surface treatment to product quality inspection and packaging, every step is carried out in strict accordance with the relevant standards. In the production process, it is also necessary to carry out various performance tests on the silicone sealing ring, such as dimensional inspection, appearance inspection, physical performance testing, etc., to ensure that the product meets the standard requirements. At the same time, manufacturers also need to establish a sound quality management system and after-sales service system to provide high-quality products and high-quality service.

The standard specifications of silicone sealing rings cover many aspects such as size, material and performance requirements. The development and implementation of these standards not only ensure the performance and use effect of silicone seals, but also promote their wide application in various fields.
