- TECHNICAL DATA SHEEt: Key characteristics and APPLICATIONS

Polyoxymethylene (POM) [Acetal]

General Information:

  • Product Name: Polyoxymethylene (POM) or Acetal or Delrin (a trademarked name by DuPont)
  • Classification: Semi-crystalline thermoplastic

 

Typical Properties:

  • Density: 1.41 – 1.43 g/cm³
  • Tensile Strength: 60 – 70 MPa
  • Elongation at Break: 20 – 30%
  • Tensile Modulus: 2,700 – 3,000 MPa
  • Melting Point: 165 – 175°C
  • Notched Izod Impact Strength: 6 – 8 kJ/m²
  • Hardness: Rockwell M80 – 90
  • Coefficient of Linear Thermal Expansion: 110 – 130 x 10^(-6) K^(-1)
  • Dielectric Constant: 3.8 – 4.2 (at 1 MHz)

 

Features and Benefits:

  • High Strength and Stiffness: Excellent mechanical strength and rigidity.
  • Low Friction: Self-lubricating properties, making it ideal for parts where low friction is required.
  • Chemical Resistance: Resistant to many solvents, chemicals, and hydrocarbons.
  • Dimensional Stability: Low moisture absorption resulting in excellent dimensional stability.
  • Fatigue Resistance: Excellent resistance to cyclic fatigue.
  • Electrical Insulation: High dielectric strength making it suitable for electrical components.

 

Applications:

  • Industrial: Gears, bearings, bushings, fasteners, and conveyor components.
  • Automotive: Fuel systems components, door handles, and control systems.
  • Consumer Goods: Zippers, appliance parts, toys, and window mechanisms.
  • Medical: Precision components for medical devices.
  • Electrical: Insulating components, connectors, and housing.

 

Processing Methods:

  • Injection Molding (components, intricate parts)
  • Extrusion (rods, tubes, and profiles)
  • Machining (precision parts)

 

Environmental Impact and Recycling:

  • POM can be recycled, but care must be taken to prevent contamination with other polymers.
  • Incineration of POM produces formaldehyde, CO₂, and water, so effective emission control is essential.
  • There are initiatives to improve POM recycling through advanced sorting and processing techniques.

 

Storage and Handling:

  • Store in a cool, dry place away from direct sunlight.
  • Handle with care to avoid contamination, especially if planned for medical or high-precision applications.





Safety Information:

  • POM is safe for various consumer and industrial applications.
  • When processing POM, ensure proper ventilation due to the potential release of formaldehyde.
  • POM is flammable and should be kept away from open flames; when burned, it can release toxic fumes.

Note: This technical data sheet provides general information and typical values for POM. Actual specifications might differ based on the manufacturer and specific product grade. Always refer to manufacturer-specific data sheets for detailed information on a particular product.
