Acetal
Acetal is an excellent general purpose thermoplastic. It is commonly used for bushings, bearings, rollers and gears because it has high tensile strength, stiffness and excellent sliding properties. Acetal has very good dimensional stability and it machines exceptionally well making it perfect for precision components. Acetal is recommended for underwater components due to its low moisture absorption, and it is FDA approved.
Acetal applications:
- Bushings
- Sliding components
- Gear wheels
- Electrical insulators
- Valves and valve bodies
- Precision Gears
- Bearings with tight tolerances
- Snap fit assemblies
- Parts which operate in water between 60° to 90° C
Key Features of Acetal
- High hardness and stiffness
- Very high mechanical properties
- Excellent creep resistance and dimensional stability
- Excellent dielectric properties
- Low co-efficient of friction
- Low water absorption
- Easy to machine.
