Applications Differences:

 

1. Automotive

In the automotive sector, while copolymer POM is suitable for parts that require superior heat stability and chemical resistance, homopolymer POM is typically favored for applications demanding strong mechanical strength and wear resistance.

2. Medical

For medical applications, copolymer POM is often the preferred choice due to its biocompatibility and ability to withstand cleaning solvents, ensuring safety and reliability in healthcare settings.

3. Electronics

In electronics and electrical engineering, copolymer POM is commonly used where higher chemical and heat resistance is needed, making it an excellent option for various components.

CHARACTERISTICS OF POM

 

Because of its many well-known qualities, polyoxymethylene is an excellent choice for precision engineering applications. Let's examine each of these characteristics in more detail:

Mechanical Properties

• High Strength and Stiffness: POM exhibits remarkable tensile strength, with values typically ranging from 60 to 75 MPa for homopolymers and slightly lower for copolymers. Its stiffness can reach up to 3,400 MPa, making it suitable for structural applications.
• Impact Resistance: POM has good impact strength, allowing it to withstand sudden shocks without significant damage, which is crucial for mechanical components.

Dimensional Stability

• Low Shrinkage and Creep Resistance: POM maintains dimensional stability under varying temperatures and humidity levels. Its shrinkage rate is generally between 1.2% and 3.5%, depending on the formulation used. It also shows low creep under long-term loads, ensuring that it retains its shape over time.

Friction and Wear Resistance

• Low Coefficient of Friction: POM has a low coefficient of friction, which enhances its performance in sliding applications such as gears and bearings. This property minimizes wear and prolongs the life of components made from POM.

Thermal Properties

• Temperature Range: POM can operate effectively in a wide temperature range, with melting temperatures around 166°C for copolymers and 178°C for homopolymers. It remains stable at temperatures as low as -40°C.
• Heat Resistance: It can withstand short-term exposure to temperatures exceeding 100°C without significant degradation, making it suitable for various high-temperature applications.

Chemical Resistance

• Solvent and Fuel Resistance: POM is resistant to many solvents, fuels, and chemicals, making it ideal for use in environments where exposure to such substances is common. However, it can be affected by strong acids and bases.
• Low Hygroscopicity: With a water absorption rate of about 0.22% to 0.25%, POM exhibits low hygroscopicity, which helps maintain its mechanical properties in humid conditions.

Electrical Properties

• Good Dielectric Strength: POM has excellent electrical insulation properties, making it suitable for electrical and electronic applications. Its high dielectric strength ensures safe operation in various electrical environments.

Processing Characteristics

• Ease of Machining: POM can be easily machined into precise shapes using conventional methods, allowing for the production of intricate parts with tight tolerances.
• Narrow Processing Temperature Range: The processing temperature for POM is relatively narrow (170°C to 215°C), requiring careful control during manufacturing to avoid degradation.
