Delrin® products in general offer slightly higher mechanical properties then "copolymer" acetal products such as Acetron® GP, but may contain a lower density center, especially in large cross sections. Many grades of Delrin® are FDA, USDA, NSF, Canada AG and 3A-Dairy compliant.
Bearings made of Delrin® AF Blend sustain high loads when operating at high speeds and show reduced wear. These bearings are also essentially free of slip-stick behavior because the static and dynamic coefficient of friction are closer than with most plastics. Delrin® AF Blend retains much of the strength that is inherent in unmodified Delrin® acetal. Some properties are changed due to the addition of the softer PTFE fiber. The natural color of Delrin® AF Blend is dark brown.
Other attributes of Delrin® AF Blend Acetal products include:
- Low moisture absorption
- High strength, stiffness
- Ideal for machined parts where low friction and long life is important
- Easy to machine
- Excellent dimensional stability
- Enhanced wear and friction properties over standard acetals
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.
