POM

POM material — short for polyoxymethylene — is a semi-crystalline engineering thermoplastic engineered for precision, low friction, and long-term dimensional stability. It belongs to the acetal family and is supplied by Ready Plastics as POM sheet, POM rod, and tube in a range of stock sizes. POM plastic is specified across industrial automation, automotive, fluid handling, and electronics manufacturing wherever tight tolerances and consistent mechanical performance are required.

POM delivers a combination of high stiffness, low moisture absorption, and a naturally low coefficient of friction that makes it ideal for gears, bushings, cams, slides, and valve components. Its excellent wear resistance supports long service intervals in sliding and rotating assemblies, and its clean machinability means parts can be produced to tight dimensional tolerances on conventional CNC and manual equipment.

Grade families. POM plastic is commercially available in two primary forms. POM-C (copolymer) introduces a comonomer into the polymer chain to improve chemical resistance and thermal stability, making it the standard choice for general-purpose applications. POM-H (homopolymer) achieves higher crystallinity, which raises tensile strength, flexural strength, and fatigue resistance — the preferred selection for mechanically demanding environments. Each family is further extended by filled and modified grades: lubricated grades reduce friction further; reinforced grades add structural rigidity; stabilized grades extend outdoor life; and static-dissipative grades protect ESD-sensitive processes.

Stocking and supply. Ready Plastics maintains inventory of POM plastic in both copolymer and homopolymer forms, cut to order for fast fulfillment. Whether your application calls for standard POM-C sheet or a specialty modified grade, Ready Plastics provides the material expertise and stock depth to support design, prototyping, and production runs. See the grade-specific pages for full property data and application guidance.
