As a semi-crystalline
material, acetal is characterized by a low coefficient of friction and good wear
properties-especially in
wet environments. Because acetal absorbs minimal amounts of moisture, its physical properties remain constant in
a variety of
environments. Low moisture absorption gives excellent dimensional stability for close-tolerance machined parts.
In high moisture
or submerged applications, acetal bearings outperform nylon 4 to 1. Acetal is ideally suited for close tolerance
mechanical parts
and electrical insulators which require strength and stiffness. It also offers resistance to a wide range of chemicals
including
many solvents. Alro Plastics offers both homopolymer and copolymer grades of acetal including three enhanced bearing
grade materials.
Features:
- Low moisture absorption
- High strength and stiffness
- Easy to machine
- Dimensionally stable for tight tolerances
- No centerline porosity
- FDA, USDA, NSF, Canada AG and 3-A Dairy compliant
Acetal Applications:
- Bearings and bushings
- Structural keels
|
- Electrical components
- Gears and rollers
|
Engineering Note:
In general, acetals do not perform as well in abrasive wear applications as nylons. Compensation for moisture
related growth generally allows nylons to be used for wet, abrasive applications. If your application requires
dimensional consistency in an abrasive, high humidity or submerged environment, Ertalyte® PET-P will often offer
improved performance.
