About the material POM
Following are the characteristics of POM materials:
- High strength and rigidity
- Good wear resistance
- Good chemical resistance
- Good dimensional stability
- Excellent electrical properties
- Low water absorption
- High temperature resistance
Available Materials
POM is an engineering thermoplastic with high stiffness, high precision, low friction and easy processing. It is often used to make precision parts that require high stiffness, low friction and excellent dimensional stability.
Following are common POM plastic processing grades：
100T Tough Grade
Has high viscosity and provides excellent toughness and durability.
100AF
Has a high viscosity for applications requiring higher abrasion resistance.
100ST
A super tough grade that provides higher impact strength and durability.
500P
Injection grade with medium to high viscosity for applications requiring good flow and moldability.
900P
Injection molding grade, high viscosity, for applications requiring high abrasion resistance.
500CL
Wear grade for applications requiring high abrasion resistance and durability.
525GR
Reinforced grade, medium viscosity, reinforced with glass fiber to provide higher strength and rigidity.
527UV
Glass fiber reinforced grade, high stiffness, low warpage, for applications requiring good dimensional stability.
107UV
UV resistant grade, provides protection against UV rays for extended service life.
Note: These grades are based on the physical and chemical properties of the POM material, such as toughness, viscosity, abrasion resistance, rigidity, etc., to meet different needs. Selecting the right grade of POM material for CNC machining is critical to ensure product performance and longevity.
Applications for POM plastic
POM can be used to manufacture a variety of high-strength, high-rigidity parts, such as bearings, gears, sliders, pneumatic components and so on. In addition, POM can also be used to manufacture molding molds, such as injection molds, blow molds, etc.
Because POM has excellent abrasion resistance and chemical resistance, it is widely used in automobile manufacturing. For example, engine valve guides, valve stems, oil seals and other components.
POM has good electrical insulation properties and stable dielectric constant, so it can be used in the manufacture of electronic components and electrical accessories, such as connectors, sockets, switches and so on.
Due to good biocompatibility and mechanical properties, it is widely used in the medical field, POM can be used in the manufacture of medical devices and human implants, such as joint prostheses, dental implants, etc.
In addition to the above applications, POM can also be used to manufacture sports equipment, furniture, toys and other daily necessities.

Frequently Asked Questions
POM, also known as acetal or polyacetal, is a thermoplastic material known for its exceptional strength, stiffness, toughness, and low coefficient of friction. Delrin belongs to the wider category of POM plastics and is a particular brand of acetal. Despite different manufacturers, Delrin and other POM acetal materials share similar properties. POM is commonly used as a substitute for metals in mechanical parts due to its high wear resistance, low friction, and resistance to abrasion, chemicals, and moisture. Additionally, it can withstand a wide range of temperatures.
POM can be CNC machined into complex shapes and is available in various grades with different properties, such as enhanced stiffness or improved chemical resistance, to suit different applications. It is used in a wide range of industries, including automotive, electrical, medical, and consumer goods.

The choice of POM or ABS depends on the specific application requirements. For example, for applications requiring high mechanical strength, wear resistance, and dimensional stability, POM may be a better choice. ABS, on the other hand, may be more appropriate for applications requiring good surface gloss, ease of processing, and a wide range of applications. Therefore, it is not possible to generalize that POM is better than ABS plastic, but rather, the right material should be selected based on specific application scenarios and needs.
