At Aetna Plastics, we provide engineering-grade thermoplastics that deliver performance where it counts. Acetal, also known by the brand name Delrin®, is a high-performance plastic renowned for its strength, stiffness, and low friction. Whether you’re machining precision parts or building durable mechanical components, Acetal offers an ideal balance of mechanical properties and workability.
What is Acetal (Delrin®)?
Acetal is a semi-crystalline thermoplastic available in both homopolymer (Delrin®) and copolymer grades. Known for its high strength, rigidity, and excellent dimensional stability, Acetal is commonly used in precision engineering applications. It features a low coefficient of friction, good wear resistance, and outstanding machinability—making it a favorite for gears, bearings, bushings, and other moving parts.
Why Choose Polypropylene?
Acetal stands out as a go-to material for tight tolerance, load-bearing, and low-friction applications.
Key Properties:
- High Strength & Rigidity: Maintains shape under load without creeping
- Low Friction: Excellent for parts requiring smooth, sliding movement
- Superior Machinability: Cuts cleanly and holds tight tolerances
- Moisture & Chemical Resistance: Performs well in wet or chemically aggressive environments
- Dimensional Stability: Low moisture absorption means consistent performance
- FDA Compliant Grades: Available for food and beverage applications
Standard Shapes and Forms Available
Aetna Plastics offers Acetal in a variety of forms to support both standard and custom machining:
- Sheet: Standard and cut-to-size thicknesses
- Rod: Available in a wide range of diameters
- Tube: Custom configurations available on request
- Machined Parts: CNC-fabricated components based on your drawings or specs
Applications of Acetal
Acetal’s unique blend of stiffness, low wear, and dimensional reliability makes it ideal for:
- Mechanical Components: Gears, pulleys, bushings, and bearings
- Fluid Handling Systems: Valves, pump components, and seals
- Automotive: Fuel system parts, window mechanisms, and interior trim
- Food Processing: Rollers, scrapers, and conveyor components (FDA grades)
- Electrical & Electronics: Insulators and structural components
Colors and Finishes Available
Acetal is typically available in natural (white), black, and blue. Specialty colors or grades (such as FDA-compliant blue or anti-static black) can be ordered depending on your specific application. Most Acetal sheets and rods have a smooth finish ideal for machining and cleanability.
