| Definition | Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. |
|---|---|
| Mechanical Properties: | High strength, hardness, and rigidity at temperatures as low as -40°C. Its tensile strength typically ranges from 55 to 80 MPa (8,000 to 12,000 psi) depending on the grade. |
|
Density: |
The density of POM ranges from 1.41 to 1.43 g/cm³. |
| Thermal Properties |
polyoxymethylene melting point is between 165 and 175°C (329 to 347°F) and the glass transition temperature is around -50 to -40°C. |
|
Chemical Resistance: |
Good resistance to solvents, fuels, and many chemicals; however, it is not resistant to strong alkalis and oxidants. |
|
Wear Resistance: |
Low coefficient of friction, making it suitable for applications involving moving parts. |
| Appearance: | Generally opaque white due to its high crystalline composition, but it can be produced in various colors. |
|
Applications |
They are used in high-performance engineering components like gear wheels, eyeglass frames, ball bearings, ski bindings, fasteners, gun parts, knife handles, and lock systems. Common in automotive and consumer electronics industries. |
Polyoxymethylene (POM) offers several advantages that make it a popular choice in various industries and applications. Here are some of the key advantages of POM:
1. Excellent Mechanical Properties: POM exhibits high strength, stiffness, and toughness, providing exceptional mechanical performance and load-bearing capabilities. It maintains its shape and resists deformation even under high loads or impact forces.
2. Dimensional Stability: POM has excellent dimensional stability, meaning it retains its shape and size over a wide range of temperatures and in humid environments. This property ensures precise and consistent performance in various operating conditions.
3. Low Friction and Wear Resistance: POM has a low coefficient of friction, which reduces wear and enables smooth movement in sliding or rotating applications. It exhibits excellent wear resistance, making it suitable for components subjected to repetitive motion or contact with other surfaces.
4. Chemical Resistance: POM demonstrates good resistance to solvents, fuels, and many chemicals, making it suitable for applications where exposure to harsh chemicals is expected. It maintains its properties and integrity in challenging chemical environments.
5. Electrical Insulation: POM exhibits good electrical insulation properties, including high dielectric strength and low dissipation factor. It is widely used in electrical and electronic applications to provide insulation and prevent electrical leakage.
6. Easy Machinability: POM is a highly machinable material, allowing for precise and complex part manufacturing. It can be easily shaped, drilled, milled, or turned, making it a preferred choice for components with intricate geometries.
7. Resistance to Moisture Absorption: POM has low moisture absorption, which helps maintain its dimensional stability and mechanical properties even in humid or wet environments.
8. Self-lubricating: POM has inherent self-lubricating properties, reducing the need for external lubrication in certain applications. This feature contributes to low friction, extended part life, and reduced maintenance requirements.
9. Good Thermal Stability: POM exhibits good thermal stability, allowing it to withstand a wide temperature range without significant degradation. It retains its mechanical properties at both low and high temperatures.
10. FDA Compliance: Some POM grades are approved for food contact applications and comply with FDA regulations. This makes them suitable for use in food processing equipment, packaging, and other related applications.
