DELRIN® - ACETAL HOMOPOLYMER
Delrin®, a homopolymer acetal, is also manufactured and stocked in rod and plate. It offers slightly higher mechanical properties than Acetron® GP Acetal, but may contain a low-density center, especially in larger cross-sections. Copolymer acetal also offers better chemical resistance than homopolymer acetal. Delrin® is ideal for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal.
Alro Plastics offers both homopolymer (Delrin®) and copolymer (Acetal and Acetron® GP) grades of acetal including enhanced bearing grade materials. Acetron® GP acetal is porosity-free and offered as our standard general purpose grade. For slightly higher mechanical properties, we offer a broad size range of the homopolymer acetal (Delrin®) products. For improved frictional properties PTFE-enhanced Delrin® AF products are available.
Key Benefits:
- Low moisture absorption
- High strength, stiffness
- Easy to machine
- FDA, USDA, NSF, Canada AG, and 3-A Dairy compliant
Product Industries:
- Aerospace and Defense
- Chemical Processing
- Food and Dairy
- Electronics and Printed Circuits
- Marine

Engineering note:
In general, acetals do not perform as well in abrasive wear applications as nylons. Compensation for moisture related growth generally allows Nylatron® 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.
