Acetal vs. Delrin: Similarities and Differences

When it comes to technical plastics, acetal and Delrin are two commonly used materials that share several similarities. Acetal, also known as polyoxymethylene (POM), is a semi-crystalline engineering thermoplastic widely employed as a substitute for metal parts in various manufacturing processes. It offers exceptional characteristics such as high friction, dimensional stability, hardness, and durability, making it an excellent choice in industrial applications.

On the other hand, Delrin, which is the trade name for acetal homopolymer, boasts enhanced properties compared to acetal. Delrin exhibits higher tensile and impact strength, improved stiffness, fatigue and creep resistance, and a more crystalline structure, resulting in superior overall performance.

The molecular composition of these materials contributes to their divergent properties. Delrin possesses a higher crystal structure order and better bond density between crystalline regions, attributing to its exceptional mechanical and structural properties.

Key Similarities:

  • Both acetal and Delrin are technical plastics used in a wide range of applications.
  • They offer high friction, dimensional stability, and durability.
  • Acetal and Delrin exhibit excellent chemical resistance to hydrocarbons, solvents, and neutral chemicals.

Key Differences:

  • Delrin has higher tensile and impact strength compared to acetal.
  • Delrin has enhanced stiffness, fatigue and creep resistance.
  • Delrin possesses a more crystalline structure, resulting in improved overall performance.

To further illustrate the differences between acetal and Delrin, refer to the table below:

Properties Acetal Delrin
Tensile Strength (MPa) ≈ 62-79 ≈ 66-80
Density (g/cm³) ≈ 1.41-1.43 ≈ 1.41-1.43
Impact Strength (kJ/m²) ≈ 4-5 ≈ 5-7
Hardness (Rockwell M) ≈ 80-95 ≈ 80-95

Acetal vs. Delrin

By understanding the similarities and differences between acetal and Delrin, manufacturers can make informed decisions about which material is best suited for their specific applications. While acetal offers excellent properties, Delrin’s enhanced characteristics make it a preferred choice in demanding industrial environments where higher strength, stiffness, and durability are required.
