Understanding the Difference between POM-C and POM-H

In the world of polyoxymethylene (POM), two distinct variations stand out: copolymer acetal (POM-C) and homopolymer acetal (POM-H). The disparity between these two types lies within their molecular structures, which is the result of the different polymerization methods used during production.

POM-C is created through the process of polymerizing two different monomers, leading to a more amorphous structure. On the other hand, POM-H is formed by polymerizing a single monomer, resulting in a regular crystalline molecular structure with a higher degree of crystallinity compared to POM-C.

These differences in molecular structure give rise to variations in performance properties between POM-C and POM-H. POM-H showcases superior mechanical performance, including enhanced hardness, stiffness, tensile strength, and compressive strength. Conversely, POM-C offers better chemical resistance and can withstand a broader range of chemicals.

By understanding the distinction between POM-C and POM-H, industries in Singapore can make informed decisions when selecting the appropriate type of POM for their specific applications.

POM-C and POM-H

Exploring the Thermal Properties of POM

Polyoxymethylene (POM) offers a range of thermal properties that contribute to its suitability for various applications. Understanding these properties is crucial for harnessing the full potential of POM in industries across Singapore.

Heat Deflection Temperature

The heat deflection temperature (HDT) is an important characteristic of POM, indicating its resistance to deformation under heat. POM-C has an HDT of 100°C, while POM-H offers a higher HDT of 110°C. This property ensures that POM components maintain their structural integrity even at elevated temperatures, making it an ideal choice for applications in demanding thermal environments.

Melting Point

The melting temperature of a material determines its transition from a solid to a liquid state. POM-C has a melting point of 165°C, while POM-H exhibits a higher melting point of 180°C. This high melting point enables POM to withstand elevated temperatures and maintain its structural stability, making it suitable for applications where thermal resistance is essential.

Thermal Conductivity

POM-C and POM-H exhibit similar thermal conductivity values, with POM-H having a slightly higher conductivity. This property is crucial for applications requiring efficient heat transfer. POM’s ability to conduct and dissipate heat effectively ensures optimal performance and prevents overheating in critical components.

Coefficient of Linear Thermal Expansion

The coefficient of linear thermal expansion (CLTE) measures the degree to which a material expands or contracts with changes in temperature. POM-H has a lower CLTE compared to POM-C, making it more suitable for high-temperature applications that demand dimensional stability. POM-H’s lower expansion rate minimizes the risk of warping or distortion, allowing for precise and consistent manufacturing.

Overall, the thermal properties of POM, including its heat deflection temperature, melting point, thermal conductivity, and coefficient of linear thermal expansion, make it a reliable and versatile material for a wide range of applications in Singapore’s industries.

Understanding the Mechanical Properties of POM

POM, also known as polyoxymethylene, exhibits exceptional mechanical properties that make it a preferred material for various applications. Let’s explore some of its key properties:

Density

POM has a high density, ranging from 1.41g/cm³ to 1.43g/cm³. This high density contributes to its strength and stability, making it suitable for structural components.

Coefficient of Friction

One of the standout characteristics of POM is its low coefficient of friction. This property makes it an ideal choice for applications where reduced friction is essential, such as gears, bearings, and sliding mechanisms.

Tensile Strength

POM exhibits high tensile strength, which is the ability to withstand pulling forces without breaking. POM-C has a tensile strength of 66 MPa, while POM-H demonstrates an even higher tensile strength of 78 MPa. This strength ensures the durability and reliability of POM components.

Modulus of Elasticity

The modulus of elasticity refers to a material’s stiffness. POM has a high modulus of elasticity, indicating its rigidity and resistance to deformation under stress. This property makes POM suitable for applications where dimensional stability and structural integrity are crucial.

Hardness and Impact Strength

POM exhibits high hardness and impact strength. Its hardness ensures resistance to wear and tear, while its impact strength allows it to withstand sudden forces or impacts without breaking. These properties make POM highly durable and long-lasting, particularly in demanding applications.

Flexural Strength and Flexural Modulus

POM demonstrates excellent flexural strength and flexural modulus. Flexural strength refers to a material’s ability to resist bending without fracturing, while flexural modulus measures its resistance to deformation under bending stress. POM’s high flexural strength and modulus make it suitable for applications where bending or flexing is common, such as hinges, levers, and springs.

POM mechanical properties

In summary, POM’s exceptional mechanical properties, including high density, low coefficient of friction, high tensile strength, modulus of elasticity, hardness, impact strength, flexural strength, and flexural modulus make it a versatile and reliable material for various applications. Its strength, rigidity, and durability ensure the longevity and performance of POM components in demanding environments.

Chemical Resistance and Compatibility of POM

POM, also known as polyoxymethylene, demonstrates excellent chemical resistance and compatibility with a wide range of substances. The two main types of POM, POM-C and POM-H, differ in their chemical resistance properties.
