Acetal

Acetal is the common name for Polyoxymethylene. It is easy to machine, holds tight tolerances, and is readily available in a variety of shapes, sizes and formulations.

Properties

Acetal provides good strength and stiffness, coupled with dimensional stability and good wear properties. It's low moisture absorbtion rate makes it a preferred choice over Nylon in many wet environments. The chemical composition, regular molecular structure and high degree of crystallinity result in a unique combination of outstanding characteristics:

• High mechanical strength and rigidity
• Toughness and high resistance to repeated impacts
• Long-term fatigue endurance
• Excellent resistance to moisture, gasoline, solvents, and many other neutral chemicals
• Excellent dimensional stability
• Good resilience and resistance to creep
• Natural lubricity
• Wide end-use temperature range
• Good electrical insulating characteristics

Applications

Automotive

• Fuel system components (gas caps, floats, pump housings, senders)
• Heavy load-bearing gears (window lifts, windshield wipers)
• Fasteners
• Window/door hardware
• Safety system components (buckles, seatbelt hardware, spools, guidetracks, clock springs)
• Loudspeaker grilles
• Control switches
• Interior trim
• Steering components
• Pillar loops
