Description
ACM is a high-performance specialty elastomer designed specifically for heat and oil resistance,serving as an ideal bridge between standard nitrile rubber (NBR) and expensive fluoroelastomers(FKM). It exhibits excellent resistance to automatic transmission fluids (ATF) and engine oils containing phosphorus-based anti-wear additives, making it a highly cost-effective solution forunder-hood applications - filling the gap where conventional rubbers tend to fail at high temperatures.
Applications
Automotive sector: Valve stem seals, oil pan gaskets, transmission seals, oil pumps.
Industrial sector: Seals and gaskets in high-temperature oil environments.
Specialty sector: Components requiring resistance to oxygenated engine oils.

FAQ
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.).
