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.


Features

  • Low moisture absorption
  • High strength and stiffness
  • Easy to machine
  • FDA, USDA, and NSF compliant
  • Ag Canada and 3-A Dairy compliant

Applications:

  • 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.
