POM as an Engineering Thermoplastic
POM (Polyoxymethylene), commonly known as acetal, is a semi-crystalline thermoplastic engineering plastic valued for its excellent mechanical properties and versatility. Its combination of strength, rigidity, and wear resistance makes it a popular choice for components requiring dependable mechanical performance and precision. Available in homopolymer and copolymer forms, POM offers a range of material characteristics to suit different industrial requirements.
Balanced Mechanical Performance
POM combines mechanical strength, stiffness, low friction, and good dimensional stability. Its excellent sliding properties and resistance to wear make it suitable for moving components exposed to repeated contact and friction. In addition, its low moisture absorption helps minimize moisture-related dimensional changes, supporting dimensional consistency in many operating environments. These characteristics make POM a versatile material for precision components that require durability, reliable movement, and consistent performance.
Industrial Applications and Product Offering
POM is widely used in mechanical engineering, automotive components, consumer products, and industrial equipment. Typical applications include gears, bearings, bushings, rollers, and other precision-engineered parts. Prochase supplies POM off-grade materials, including 100P, 500P, and 900P grades, providing options for industrial buyers seeking these specific material grades for their sourcing requirements.
