Polyacetal (POM), Polyoxymethylene (POM), or Acetal, is a high-performance engineering thermoplastic known for its exceptional mechanical properties and versatility.
Here's a detailed description:
Composition: Polyacetal is a formaldehyde-based, semi-crystalline polymer with the molecular structure (CH₂O)ₙ. It is available in both homopolymer and copolymer forms.
Properties:
High Strength and Rigidity: POM exhibits high tensile strength and rigidity, making it suitable for precision parts requiring high stiffness.
Low Friction: It has excellent wear resistance and low friction, ideal for moving parts.
Dimensional Stability: POM maintains its shape and size under varying environmental conditions.
Thermal Stability: It can withstand high temperatures without losing its properties.
Chemical Resistance: POM is resistant to many chemicals, including oils and solvents.
- Electrical Insulation: POM has good electrical insulating properties, making it useful for electronic components.
Flame Retardancy: It can be treated with flame retardants to enhance its fire resistance.
Applications: POM is used in a wide range of applications, including automotive parts, consumer electronics, medical devices, gears, bearings, and fasteners.
