Acetal Rod

Acetal is an engineering thermoplastic based on polyoxymethylene (POM) — a highly crystalline polymer valued for precision, low friction, and consistent mechanical performance. The acetal family includes two primary grades: POM-C (Acetal Copolymer) and POM-H (Acetal Homopolymer), each available as unfilled or modified variants. Ready Plastics stocks acetal plastic in sheet, rod, and tube form to support prototype and production machining needs.

Acetal combines high stiffness, low moisture absorption, and a naturally low coefficient of friction, making it a reliable choice for moving components that must hold tight tolerances over time. Its excellent wear resistance reduces maintenance intervals in sliding and rotating parts, while its superior machinability allows clean, accurate cuts on standard shop equipment. These properties have made acetal a go-to material for gears, bushings, cams, valve bodies, and fluid-handling components across industrial and automation industries.

Grade selection. The two sub-families reflect different polymerization routes. POM-C (copolymer) is produced by copolymerizing trioxane with a comonomer, yielding improved chemical resistance and thermal stability — the preferred choice for most general-purpose applications. POM-H (homopolymer) offers a higher crystallinity that translates to greater tensile strength, stiffness, and fatigue resistance, making it the preferred choice when maximum mechanical performance is required. Both families are further available in filled and modified grades — including MoS₂-lubricated, PTFE-lubricated, glass-fiber-reinforced, UV-stabilized, static-dissipative, and metal-detectable variants — to address application-specific requirements.
