When selecting acetal plastic for industrial use, it’s important to understand the difference between POM-C (copolymer acetal) and POM-H (homopolymer acetal). Though both materials fall under the acetal or polyoxymethylene (POM) family, they differ in molecular structure, performance characteristics, and processing behavior.
POM-C, or copolymer acetal, is known for its enhanced chemical resistance and lower porosity, making it suitable for applications involving moisture or aggressive cleaning agents. On the other hand, POM-H, also called homopolymer acetal, often recognized under the brand Delrin®, offers slightly better mechanical strength and stiffness, ideal for precision parts requiring high dimensional stability.
Understanding the key differences between copolymer vs homopolymer acetal will help you choose the right material for gears, bushings, bearings, and other high-performance plastic components.
Understanding the technical and performance differences between POM-C (copolymer) and POM-H (homopolymer) is essential when choosing the right material for engineering applications. Each grade has its strengths—POM-C offers better chemical resistance and dimensional stability, while POM-H provides higher stiffness and better wear performance under dry conditions. The right choice depends on your specific working environment, design requirements, and machining needs.
