POM-H
Key Features: POM-H is an acetal copolymer homopolymer that is incredibly strong, stiff, and resistant to wear, making it an excellent engineering material. Additionally, POM-H has low thermal expansion, exceptional impact strength, and high dimensional stability; therefore, it is suited for precision applications in hostile environments. Combined with high chemical resistance, machinability, and excellent sliding properties, POM-H is an ideal material for the most challenging industrial sectors.
Applications: It is well-suited for precise small parts such as bushings, electrical components, bearings, gears, fluid handling devices and tools in the food industry due to its high dimensional accuracy, chemical resistance and FDA compliance for food contact.
