Why You Need POM Sheet
POM has a wide range of applications; many equipment manufacturers purchase POM components from HANSA for assembly, while OEM factories buy POM sheets from HANSA for further processing—all due to POM’s excellent properties.
POM exhibits high rigidity, high mechanical strength, and excellent wear and fatigue resistance. It features a low coefficient of friction (0.2–0.35) and self-lubricating properties, making it ideal for sliding components subject to repetitive loading and movement.
POM has low water absorption (approximately 0.2–0.8%) and is resistant to swelling caused by moisture, allowing it to maintain high dimensional stability even in humid environments.
As a thermoplastic with stable melt flow characteristics, POM offers excellent processability. It is particularly well-suited for CNC machining; the material does not easily adhere to cutting tools and exhibits low internal stress and minimal warping, enabling the production of precision components with complex geometries and tight tolerances.
POM strikes a balance between performance and cost-efficiency. Thanks to its superior machinability and long service life, it helps reduce total system operating costs and delivers long-term economic benefits in mechanical applications.
What is the difference between POM-H and POM-C?
POM-H is a homopolymer with a tighter, more ordered molecular arrangement. Consequently, POM-H sheets offer higher strength, greater rigidity, and superior wear resistance; they are typically used for high-load gears, mechanical transmission components, and dry-friction sliding parts.
POM-C is a copolymer; the inclusion of monomers other than formaldehyde disrupts the regularity of the molecular chains, resulting in a looser molecular structure. This leads to lower internal stress, better dimensional stability, and improved resistance to hydrolysis and chemical corrosion, as well as better processing stability. It is generally used for sliding parts in humid environments, precision guide components, and the like.
When should you choose POM sheets?
POM sheets are precision engineering plastics for moving parts that offer a balanced combination of low friction, high precision, and medium-load capacity. If your project involves repetitive load-bearing movement where lubrication cannot be applied, POM sheets are the ideal choice. They are also an excellent option when high dimensional accuracy is required. However, caution is advised if the application involves strong acids or alkalis, or long-term operating temperatures exceeding 100°C, as POM sheets often cannot withstand such environments for extended periods.

What are POM Sheets used for
Due to their excellent mechanical properties, POM sheets are commonly machined into components and find applications across a wide range of industries.
Mechanical Parts
For example, components that require repetitive motion, such as gears, bushings, bearings, and sliders.
Automation
For example, components such as conveyor guide rails, wear strips, and rollers are subject to specific loads and require parts with good wear resistance.
汽车
Examples include components such as window regulators, door sliders, and fuel pumps.
Food machinery
Examples include conveyor components and cutting guides; POM is safe, non-toxic, and suitable for food contact.
Disadvantages of POM Sheet
Although POM offers a balance of cost and mechanical properties, it has certain limitations.
- It lacks high-temperature resistance; POM sheets are suitable for long-term operation only at temperatures below 100°C, with a short-term operating limit of 120°C.
- Its chemical resistance is limited, and it cannot withstand strong acids or strong alkalis.
- It is unsuitable for applications involving high impact loads.
The Differences between POM-H and POM-C
特性
POM-H offers higher strength, greater rigidity, and superior wear resistance. POM-C provides better dimensional stability, enhanced resistance to hydrolysis and chemicals, and good processing stability.
应用
POM-H is suitable for applications requiring structural strength, such as high-load gears, mechanical transmission components, high-rigidity structural parts, and dry-friction sliding components. POM-C is suitable for components requiring long-term stability and environmental resistance, such as parts for food processing machinery, components for humid environments, pump and valve parts, and precision guide elements.
Processing capabilities
POM-H is harder and causes significant tool wear, requiring regular tool maintenance and replacement; it is more brittle during cutting, necessitating careful control. POM-C is more stable, offers smoother machining, and is less prone to cracking or deformation.
POM vs Other Materials
Can POM replace metal？
POM can replace some metals, though not all. In applications involving low to moderate loads, POM can substitute for metal components such as bushings, sliders, and guides, as it operates with minimal friction and noise and requires no lubrication. It is also suitable for certain low-speed transmission gears and drive components in automation equipment, as well as for replacing metal parts in humid or corrosive environments.
Is POM better than Nylon？
Each has its own distinct advantages and is suited to different applications; neither is inherently superior to the other.
POM offers high rigidity and structural stability, making it ideal for precision components; most importantly, it has lower water absorption than Nylon.
Nylon excels in impact resistance and toughness—offering greater durability under stress—which makes it suitable for load-bearing structural applications. However, it has a higher water absorption rate; it tends to swell upon absorbing moisture, which can affect dimensional stability.
How is POM vs UHMW？
POM offers superior rigidity and dimensional stability, along with a medium-to-high load-bearing capacity. While POM already has a low coefficient of friction, UHMW’s is even lower, resulting in exceptional wear resistance; however, UHMW is less rigid and dimensionally stable, being a softer material prone to creep.
Neither POM nor UHMW absorbs much water, and neither is resistant to high temperatures. The maximum long-term service temperature is 100°C for POM and 90°C for UHMW.
When to use POM Sheet
Determining whether your application is suitable for POM sheet—or if your parts can be machined from it—is actually quite simple. Here are the key factors to consider:
- Is low friction required?
Mechanical components such as gears, sliders, and guides require smooth operation; POM offers self-lubricating properties, eliminating the need for external lubricants.
- Is dimensional stability required?
Thanks to its high rigidity and excellent dimensional stability, POM is ideal for precision CNC components and parts for automation equipment.
- What is the level of long-term load?
POM is well-suited for applications involving moderate loads, where it can operate reliably over the long term.
- Do you want to replace moving metal parts?
In certain humid or corrosive environments where metal components have a short service life, POM serves as an excellent alternative; it not only lasts longer but also reduces noise and friction.
