How does the material selection of rubber seals affect the performance?

Rubber sealThey are indispensable components in the industrial and automotive sectors, their main function is to prevent liquid or gas leaks and protect mechanical parts from contamination and corrosion. The material choice of rubber seals has a decisive impact on its performance. Different rubber materials have different physical and chemical properties, so TEC Rubber believes that selecting the right material can ensure that the seal has good temperature, chemical, oil and wear resistance under specific working conditions.

Nitrile butadiene rubberNBRIt is one of the commonly used rubber sealing materials, especially in occasions where oil resistance is required.NBRIt has excellent oil and fuel resistance and is suitable for sealing in automotive engines and transmission systems. But,NBRThe heat resistance is poor, usually only in-40℃to120℃The temperature range is used.

fluororubberFKM) is another high performance sealing material with good high temperature resistance and chemical resistance. It can be in-20℃to250℃Operates within a temperature range and is even able to withstand up to high in some cases300℃The high temperature. Fluororubbers also have good oil and oxidation resistance and are suitable for sealing applications in the aerospace and chemical industries.

Silicone rubberVMQIt has excellent high and low temperature resistance and can be used in-60℃to+200℃The temperature range remains elastic. It also has good weather aging resistance and electrical insulation, so it is often used for sealing outdoor equipment and electrical appliances.

Ethylene-propylene rubberEPDMIt also has good weather resistance and ozone resistance and is suitable for use in outdoor environments. It also has good heat and chemical resistance, but is not suitable for contact with oil substances.

Polyurethane rubberPUIt has high wear resistance and tear resistance, but also has good elasticity and oil resistance. It is often used as a seal in hydraulic and pneumatic systems.

To sum up,TEC RubberWant to tell you: the material choice of rubber seals depends on its working environment and performance requirements. The right material choice can greatly increase the life and reliability of seals, reduce maintenance costs, and ensure efficient operation of the entire system. When selecting rubber materials, factors such as temperature, pressure, type and concentration of chemical media, and possible mechanical stress must be taken into account to ensure that seals can provide optimal performance under specific conditions.
