Analysis of 7 common rubber sealing ring materials: choosing the best sealing solution

As one of the common sealing materials in the industrial field, rubber seals play an important role in various application scenarios. Different rubber materials have different characteristics, so it is crucial to choose the right seal material. This article will analyze 7 common rubber seal materials to help you choose the best sealing solution.

Nitrile rubber (NBR)

Nitrile rubber is a versatile sealing material with good oil resistance, wear resistance and aging resistance. It is suitable for general industrial application environments, such as automobiles, hydraulic equipment, air conditioning systems, etc., and is one of the most common seal materials.

Fluororubber (FKM)

Fluororubber has excellent high temperature resistance, chemical corrosion resistance and oil resistance, and is suitable for sealing applications in harsh environments such as high temperature, high pressure, and corrosive media. It is commonly used in aerospace, petrochemical, automotive engines and other fields.

Propylene rubber (ACM)

Propylene rubber has good oil resistance and high temperature resistance, and is suitable for parts that require oil-resistant seals such as automotive engines, gearboxes, and lubrication systems.

Chloroprene rubber (CR)

Chloroprene rubber has good weather resistance and ozone resistance, and is suitable for outdoor environments or occasions that are greatly affected by ozone and ultraviolet rays, such as automobile tires, seals, etc.

Ethylene propylene rubber (EPDM)

Ethylene propylene rubber has excellent aging resistance, ozone resistance and corrosion resistance, and is suitable for sealing applications in special occasions such as outdoor environments and hot water systems.

Hydrogenated nitrile rubber (HNBR)

Hydrogenated nitrile rubber has good oil resistance, wear resistance and high temperature resistance, and is suitable for sealing applications in high temperature and high pressure environments such as automobile braking systems, fuel systems, and air conditioning systems.

Silicone rubber (VMQ)

Silicone rubber has excellent high temperature resistance, ozone resistance and corrosion resistance, and is suitable for sealing applications with special requirements such as high temperature and high pressure, food grade, and medical grade.

In summary, different rubber sealing ring materials have different characteristics and applicable scopes. The selection of the best sealing solution requires comprehensive consideration of factors such as the specific working environment, medium requirements, and sealing performance. I hope this article can help you better choose the right rubber sealing ring material to ensure the safe operation of equipment and systems.
