Polyoxymethylene Rod（POM Rod）

FEATURES

1、Exceptional Strength & Rigidity: POM (Acetal) rods offer high mechanical strength, stiffness, and dimensional stability, even under continuous stress.

2、Low Friction & Wear Resistance: Ideal for applications requiring smooth movement, POM has excellent abrasion resistance and self-lubricating properties.

3、Chemical Resistance: Resists solvents, fuels, and many organic chemicals, making it suitable for harsh environments.

4、Thermal Stability: Performs reliably in temperatures ranging from -40°C to 100°C (-40°F to 212°F).

5、Machinability: Easy to CNC mill, turn, or drill while maintaining tight tolerances.

6、Low Moisture Absorption: Minimal swelling or property changes in humid conditions.

Q&A

Q

What is POM Plastic (Polyoxymethylene)?

POM (Polyoxymethylene) is a high-performance engineering thermoplastic. It offers excellent stiffness, low friction, high mechanical strength, and strong resistance to wear, chemicals, and moisture.

Q

Can POM rods be machined easily?

Yes! POM is highly machinable with standard tools, producing smooth finishes with tight tolerances. Use sharp tools and proper cooling to avoid overheating.

Q

Is POM resistant to chemicals and UV light?

POM resists most solvents, oils, and fuels but degrades under strong acids/bases. It has poor UV resistance—add stabilizers or coatings for outdoor use.

Q

Where are POM plastic rods commonly used?

—Automotive parts (e.g., fuel system components, door handles).

—Industrial machinery (gears, bushings, conveyor belts).

—Consumer goods (zippers, locks, kitchen appliances).

—Medical devices (instruments requiring sterilization).

—Electrical insulators (low conductivity).

Q

Can POM be glued or welded?

POM is difficult to bond with adhesives—specialized surface treatments or welding (hot-air, friction) are recommended.
