POM Copolymer Film

POM Copolymer Film offers high stiffness, low friction, and excellent dimensional stability, combined with improved resistance to thermal and oxidative degradation compared to homopolymers. Its smooth surface, wear resistance, and chemical inertness make it suitable for precision engineering, automotive, and industrial applications. Industries use POM copolymer film for low-friction slide surfaces, chemically resistant liners, and wear pads. Specific applications include precision shims in machinery, chemical barrier layers in pumps, and low-wear contact surfaces in conveyor systems. In research, the film is used to study tribological performance under varied lubrication regimes, evaluate dimensional stability in thermomechanical cycling, and develop composite laminates with enhanced durability. Its combination of mechanical integrity, chemical resistance, and form adaptability ensures ongoing use in advanced industrial and engineering systems.
