What Is AEM Rubber?

AEM rubbers (Ethylene acrylic elastomers) are synthetic rubbers composed of both ethylene and acrylic monomers. The ethylene imparts good low-temperature properties, while the acrylic portion improves the oil resistance. The combination of a saturated backbone with polar side groups also provides good resistance to heat, ozone (weathering), and many chemicals.

 

Besides excellent heat and ozone resistance, AEMs have outstanding vibration dampening and good dynamic and abrasion properties over a wide temperature range. However, AEMs are more expensive than most standard elastomers including NR, NBR, CR, EPDM, and SBR.

 

Properties Of Ethylene Acrylic Elastomers (AEM Rubber)

These are some of the properties of AEM rubber compounds:

 

Material Processing

The manufacturing technologies of these types of compounds are the traditional compression and injection molding, extrusion, calendering, and coating processes.

Some specialties require exclusive reticulation agents that take advantage of specific chemical properties.

 

What Is AEM Rubber Typically Used For?

AEM elastomers are primarily used where combined resistance to ozone, heat, and oils is required. They are sometimes a good alternative to more expensive heat-resistant elastomers such as fluorocarbon polymers (FKM), silicones (VMQ), and fluoro-silicones (FVMQ) for elevated temperature applications (< 150 °C, < 300 °F).

 

• Turbocharger hoses and other hose applications.


• Blow-by gas and diesel particle filter sensor sheaths.


• Air management elements.


• Oil- and heat-resistant vibration dampers.


• Engine and transmission seals.


• Cylinder head cover gaskets.


• Oil filter and oil sump gaskets.


• Shift pistons.

 

Application of Automotive AEM Rubber Ring

Automotive AEM (Ethylene Acrylic Elastomer) rubber rings are widely used in the automotive industry. Here are some common application areas:

 

1. Engine system: AEM rubber O-rings are often used for sealing applications in automobile engine systems. They are used to seal various parts of the engine such as cylinder heads, valve covers, oil pans, intake manifolds, etc. AEM rubber has excellent oil, heat, and chemical resistance, providing reliable sealing performance in high temperatures and harsh engine environments.

 

2. Fuel system: AEM rubber O-rings are also widely used in automobile fuel systems. They are used to seal components such as fuel injectors, fuel filters, fuel pumps, and fuel storage tanks. AEM rubber has better resistance to fuel and chemicals and can effectively prevent fuel leakage and pollution.

 

3. Cooling system: In automobile cooling systems, AEM rubber O-rings are used to seal radiators, coolant sensors, coolant pumps, and other components. They can withstand the high temperatures and chemical corrosion of the coolant, ensuring the tightness and reliability of the system.

 

4. Air conditioning system: AEM rubber O-rings are also used in automobile air conditioning systems. They are used to seal components such as compressors, condensers, evaporators, and pipe joints. AEM rubber has good heat and corrosion resistance and can withstand the effects of high temperatures and chemicals.

 

5. Transmission system: In automobile transmission systems, AEM rubber O-rings are used to seal key components such as transmissions, drive shafts, and differentials. They can withstand high temperatures, high pressures, and chemical corrosion, ensuring the reliability and sealing performance of the drive system.

 

Overall, Automotive AEM rubber O-rings are widely used in the automotive industry for sealing applications in critical components such as engine systems, fuel systems, cooling systems, air conditioning systems, and transmission systems. Their excellent performance and durability make them one of the first choices of automotive manufacturers and suppliers.
