Typical Uses
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.
 
  • Bearing and Bushings
  • Structural keels
  • Electrical components
  • Gears and Rollers

General grade

Acetal plastics are ideally suited for close-tolerance mechanical parts and electrical insulators, which require strength and stiffness. Acetal plastics also resist a wide range of chemicals, including many solvents. Alro Plastics offers both homopolymer and copolymer grades of acetal, including three enhanced bearing grade materials.
 

Acetal Plastic Properties

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 moisture, its physical properties remain constant in various 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.

The Alro Advantage

Alro is a direct supplier and distributor of premium acetal copolymer plastics. Whatever your project requires, we can provide high-quality acetal plastic products to meet your specifications. Request a quote, or call us at 888-888-2576 and we will help you find the products you need.

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.
