POM is a high-performance engineering thermoplastic known for its excellent dimensional stability, high stiffness, low friction, and good wear resistance. It is commonly used as a metal replacement in precision parts that require high mechanical strength and low moisture absorption. POM performs well in applications involving moving components and exposure to fuels or solvents.
