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.

Acetal Copolymer Plastic Options:

Acetal copolymer plastics are available in various formats to meet your application needs. Standard acetal copolymer plastic options include:

  • Sheet
  • Plate
  • Rod
  • Tubing
  • Bushings

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.

Acetal’s beneficial features include:

  • 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 Copolymer Plastic Applications:

Acetal plastics are ideally suited for the following applications and environments:
  • Bearings and bushings
  • Electrical components
  • Structural keels
  • 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.
