POM material, also known as acetal plastic, is a semi-crystalline thermoplastic that stands out for its high mechanical strength and rigidity. POM boasts excellent sliding properties, excellent wear resistance, and low moisture absorption. The dimensional stability of the material, along with notable fatigue resistance and excellent machinability, make POM plastic an extremely versatile engineering material, particularly suitable for the creation of complex components.
Technical POM plastic can be divided into acetal homopolymer (POM-H) and acetal copolymer (POM-C), due to their slight structural differences which lead to higher crystallinity for POM-H. Known by the brand name Delrin from DuPont de Nemours, Inc., POM-H presents a slightly higher density, hardness, and strength compared to the copolymer. However, the excellent mechanical properties of Delrin are not the only advantage; it also offers better heat resistance due to its higher melting point. POM-C material, on the other hand, is characterized by better chemical resistance. Both POM polymers exhibit properties suitable for contact with food, making them suitable for use in the food industry, unless the use of aggressive chlorinated detergents is expected. In such circumstances, POM-C should be the preferred material.
