Acetal [POM: Polyacetal]
This is very well suited for machining on automatic lathes and is particularly recommended for mechanical precision parts.
Main Characteristics:
- High mechanical strength, stiffness, hardness and toughness
- Excellent resilience
- Good creep resistance
- High impact strength, even at low temperatures
- Very good dimensional stability (low water absorption)
- Good sliding properties and wear resistance
- Excellent machinability
- Good electrical insulating and dielectric properties
- Physiologically inert (suitable for food contact)
- Not self-extinguishing
Applications:
Gear wheels with small modulus, cams, heavily loaded bearings and rollers, bearings and gears with small clearances, valve seats, snapfit assemblies, all kinds of dimensionally stable precision parts for machine construction, electrically insulating components, parts which operate continuously in water of 60 – 80°C.
