The advantages and disadvantages of silicone rubber sealing ring in high temperature environment and the scope of application are detailed

 

Silicone rubber seals are widely used in various industrial fields because of their excellent performance in high temperature environment. This paper will discuss the advantages, disadvantages and scope of application of silicone rubber seals in high temperature environment in detail to provide in-depth understanding and guidance for practitioners in related industries.

 

 

 

advantage

 

 

 

Excellent high temperature resistance: silicone rubber seals can maintain good elasticity and sealing performance under long-term high temperature (usually up to more than 200 degrees Celsius), and are not easy to harden or fail.

 

 

 

Excellent oxidation resistance and aging resistance: silicone rubber has high oxidation resistance, can be used in the oxygen and ozone environment for long-term stability, and is not easy to be oxidized and degraded.

 

 

 

Excellent electrical insulation performance: silicone rubber has good electrical insulation characteristics, suitable for the sealing of electrical equipment and electronic products, can effectively block the current and electrical components of the water.

 

 

 

Good impact and vibration resistance: silicone rubber sealing ring has good flexibility and elasticity, and can maintain a stable sealing effect under mechanical vibration and impact load.

 

 

 

shortcoming

 

 

 

Low strength and poor tear resistance: compared with other sealing materials, the physical and mechanical properties of silicone rubber are slightly inferior, and the tear resistance and wear resistance are poor.

 

 

 

Higher price: Due to the high manufacturing process and material costs of silicone rubber, its price is usually more expensive than that of general rubber seals.

 

 

 

Scope of application

 

 

 

Automotive manufacturing: Used in automotive engines, exhaust systems, hydraulic systems and other parts that require high temperature seals.

 

 

 

Electronic and electrical industry: suitable for sealing of electronic equipment, electrical components and high temperature thermoelectric modules.

 

 

 

Food and pharmaceutical industry: Because of its good biocompatibility, silicone rubber can be used for sealing food processing equipment and medical devices.

 

 

 

Aerospace field: Applied to the sealing of aeroengines, aerospace devices and high-temperature liquid handling systems.

 

 

 

Sum up

 

 

 

Silicone rubber seals have been widely used in various high temperature environments because of their excellent high temperature resistance and aging resistance. Understanding its advantages and disadvantages and scope of application helps to correctly select and apply silicone rubber seals to ensure the long-term stable operation of equipment and systems.
