This crystallinity makes POM plastic material highly resistant to wear and capable of withstanding significant stress without deforming.

Molecular Properties of POM Plastic

The molecular structure of polyoxymethylene results in a low coefficient of friction, making it an ideal material for applications where sliding and moving parts are involved. The strong intermolecular forces within polyacetal material contribute to its ability to maintain shape and stability under mechanical stress. This toughness is particularly beneficial in high-performance environments, such as automotive components and precision machinery.

High Mechanical Strength and Durability

One of the primary reasons POM plastic is valued in industrial applications is its exceptional mechanical strength. It can handle heavy loads and maintain its integrity in high-stress environments, making it a go-to material for gears, bearings, and bushings. Additionally, the high durability of polyoxymethylene material ensures that it performs well over extended periods of time without significant wear or degradation.

Resistance to Impact and Wear

Polyacetal plastic stands out for its ability to resist impact and wear. This makes it a superior choice in environments that demand tough, wear-resistant materials, such as electronic components and automotive parts. Its resilience against abrasion and its ability to withstand repeated mechanical stress without losing form further enhance the performance of POM plastic in rigorous applications.

Applications that Rely on the Strength of POM

Industries such as automotive, consumer electronics, and industrial machinery rely on the toughness of polyacetal to produce parts that require dimensional stability, high strength, and low friction. From gears and rollers to structural components, POM plastic ensures reliable performance in high-stress situations where failure is not an option.

This combination of molecular stability, high mechanical strength, and resistance to wear makes POM plastic one of the most durable and tough materials for industrial and engineering applications.

Acetal Copolymer vs. Homopolymer: Which POM Plastic is Stronger?

POM plastic exists in two main forms: homopolymer and copolymer, both of which are widely used in industrial applications but possess distinct properties that make them suitable for different uses. Understanding the differences between acetal copolymer and homopolymer is crucial when selecting the right material for a given application.

What is POM Homopolymer?

POM homopolymer, often referred to as Delrin, is made from pure polyoxymethylene. Its molecular structure consists of single repeating units, giving it higher crystallinity and mechanical strength. POM homopolymer excels in applications requiring high tensile strength, rigidity, and low friction, making it ideal for precision gears, bearings, and automotive components. The high degree of crystallinity in POM homopolymer enhances its dimensional stability, but this also makes it more susceptible to degradation in high-moisture environments.

What is Acetal Copolymer?

In contrast, POM copolymer is formed by copolymerizing polyoxymethylene with other chemical compounds, resulting in a structure that is less crystalline but more chemically stable. Acetal copolymer offers better resistance to moisture, chemicals, and thermal degradation compared to its homopolymer counterpart. Its lower crystallinity means it has slightly reduced mechanical strength, but it compensates with superior environmental resistance, making it a better choice for applications exposed to harsh chemicals or moisture, such as plumbing components or electrical insulation.

Which POM Plastic is Stronger?

In terms of mechanical strength, POM homopolymer is generally stronger due to its high crystallinity and stiffness, making it suitable for applications where tensile strength and dimensional accuracy are critical. However, acetal copolymer offers greater toughness in chemically aggressive environments, providing better impact resistance and flexibility when used in moisture-exposed applications.

Application-Specific Strength

For applications requiring high precision, such as mechanical gears and automotive parts, POM homopolymer is often the preferred choice due to its superior strength and stiffness. On the other hand, in environments where chemical resistance and durability are paramount, such as in plumbing or electronic components, POM copolymer is the better option due to its ability to resist moisture and chemicals while retaining sufficient strength for those applications.

Understanding the unique properties of POM homopolymer and copolymer can help industries make informed choices for optimal performance, balancing mechanical strength and environmental resistance based on specific application needs.
