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.
