The characteristics of rubber gaskets

Rubber gaskets, as a widely used sealing material, play a significant role in various industries due to their unique physical and chemical properties. This article will provide a detailed analysis of several major characteristics of rubber sealing gaskets to help readers better understand their advantages in practical applications.

1. Excellent temperature resistance

Rubber sealing gaskets have excellent temperature resistance and can maintain stable sealing effects over an extremely wide temperature range. Different types of rubber materials have varying degrees of tolerance to temperature. For instance, silicone rubber gaskets can maintain good elasticity in use at extreme temperatures ranging from -100℃ to 300℃, while fluororubber gaskets can operate effectively within the range of -20℃ to 200℃. This temperature resistance enables rubber sealing gaskets to be widely used in high or low temperature environments such as thermal machinery and aerospace.

2. Strong resistance to chemical erosion

Rubber gaskets have excellent resistance to a variety of chemical substances and can maintain their stable performance for a long time in corrosive environments such as acids, alkalis, oils and salts. For instance, nitrile butadiene rubber (NBR) is renowned for its excellent oil resistance and also has strong acid and alkali resistance, making it suitable for industries such as petroleum and chemical engineering. Fluororubber is an ideal choice in the chemical industry due to its high chemical stability, which enables it to resist the erosion of various organic solvents and strong oxidants.

3. Excellent anti-aging performance

Rubber sealing gaskets have good anti-aging performance and can maintain their original physical and chemical properties for a long time. They are not easily affected by factors such as oxidation, ultraviolet radiation and electromagnetic radiation, thus extending their service life. This characteristic enables rubber sealing gaskets to maintain stable sealing performance even in outdoor environments and harsh working conditions.

4. Excellent sealing performance

Rubber gaskets prevent the leakage of liquids or gases by filling the gaps between the sealing surfaces, forming a tightly sealed state on the contact surfaces. Its sealing performance is affected by factors such as compression deformation, gasket thickness and surface roughness, but generally speaking, rubber sealing gaskets can provide reliable sealing guarantees. Rubber gaskets play a crucial role in fields such as mechanical equipment, automotive engines, and pipe connections.

5. Diversified materials

The materials of rubber sealing gaskets are rich and diverse, including silicone rubber, nitrile rubber, fluorine rubber, chloroprene rubber, etc. Each material has its unique performance characteristics and application scenarios. For instance, silicone rubber has outstanding resistance to high and low temperatures as well as aging. Nitrile rubber is renowned for its excellent oil resistance and wear resistance. The diversity of this material enables rubber sealing gaskets to adapt to various complex usage environments and meet the demands of different industries.

Conclusion

Rubber sealing gaskets play an irreplaceable role in various industries due to their outstanding temperature resistance, chemical erosion resistance, anti-aging performance and excellent sealing performance. With the advancement of technology and the development of industry, the performance of rubber sealing gaskets will continue to improve, and their application scope will also become more extensive. It is hoped that through the introduction of this article, readers can have a deeper understanding of the characteristics of rubber sealing gaskets, and thus make more reasonable choices in practical applications.
