Polyoxymethylene (POM), also known as acetal or Delrin (a commercial brand), is a high-performance thermoplastic material renowned for its exceptional mechanical properties. It is widely used in precision engineering, automotive, and industrial applications due to its strength, durability, and low friction characteristics.
High Strength and Rigidity
One of the key properties of POM plastic is its high tensile strength and rigidity. It has excellent resistance to wear and tear, making it ideal for applications where durability is essential. This material can withstand significant mechanical stress without deforming, which is why it’s commonly used for gears, bearings, and other moving parts.
Low Friction and Wear Resistance
POM is known for its low friction coefficient, making it an excellent choice for components that experience constant motion or contact with other materials. Its inherent lubrication properties reduce wear, making it ideal for applications such as automotive parts, electrical connectors, and machinery components where low friction is critical.
Chemical Resistance
POM plastic has good resistance to a wide range of chemicals, including solvents, fuels, and oils. This makes it suitable for use in harsh environments where exposure to chemicals could degrade other materials. However, it is not resistant to strong acids or bases.
Thermal Stability
POM has a relatively high melting point of around 175°C (347°F), allowing it to maintain its mechanical properties at elevated temperatures. It also offers good dimensional stability, making it resistant to temperature-induced changes in shape.
Conclusion
Overall, POM plastic is a versatile material with excellent strength, low friction, chemical resistance, and thermal stability, making it ideal for demanding engineering applications.
