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.
