Description
AEM is a high-performance specialty elastomer known for its outstanding heat aging resistance and fluid resistance. It plays a key role in the automotive industry, particularly in powertrain and drive line applications. AEM offers an excellent combination of superior heat resistance (up to175°C+), resistance to automatic transmission fluids (ATF) and gear oils, as well as better low-temperature performance than ACM rubber. In addition, it features low smoke density emissions,meeting the safety and environmental standards of modern automotive and industrial sectors.
Applications
Automotive powertrain: Valve cover gaskets, crankcase ventilation hoses, turbocharger hoses.
Transmission system: Transmission seals, O-rings.

FQA
Q: Do you sell finished products or raw materials?
A: We only supply rubber compounds, not finished products. You can choose hardness, color, and formulation based on your product needs. We mix to order and deliver.
Q: What rubber types can you handle?
A: Common types include NR, SBR, BR, NBR, EPDM, CR, silicone rubber, fluororubber, etc., subject to actual capability.
Q: Are hardness and formulation linked?
A: No. The same hardness can be achieved with different formulations. The difference lies in tensile strength, tear resistance, compression set, oil resistance, aging resistance, etc. Tell us your application and we’ll recommend the right system.
Q: Can you compound to the customer’s formula?
A: Yes. We support toll processing with customer-supplied materials or mixing to a customer-specified formula. We can also recommend a formula based on performance requirements.
Q: How do you ensure batch-to-batch consistency?
A: Through raw material batch control, fixed mixing process parameters, and sampling tests (hardness, specific gravity, Mooney viscosity, etc.).
