Acetal provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, acetal is also characterized by a low coefficient of friction and good wear properties -- especially in wet environments.
Because acetal absorbs minimal amounts of moisture, its physical properties remain constant in a variety of environments. Low moisture absorption results in excellent dimensional stability for close-tolerance machined parts. In high moisture or submerged applications, acetal bearings outperform nylon 4 to 1. Acetal is ideally suited for close tolerance mechanical parts and electrical insulators which require strength and stiffness. It also offers resistance to a wide range of chemicals including many solvents.
We offer both homopolymer and copolymer grades of acetal including enhanced bearing grade materials. AcetronŽ 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 (DelrinŽ) products. For improved frictional properties PTFE-enhanced Delrin AF products are available.

General Applications:
Bearings and Bushings:
Acetal offers excellent stability and good wear resistance in a variety of moist environments.
Electrical Components:
Porosity-free AcetronŽ GP acetal is intricately fabricated into this electrical test part with dozens of tight tolerance machined holes required at its centerline. (Prior material: Standard Acetal)
Structural Keels:
Delrin* acetal delivers outstanding fatigue and impact resistance in this continuously loaded structural keel for a prosthetic device. (Prior materials: Nylon, Elastomer)
Gears:
AcetronŽ GP maintains tight tolerances despite environmental and clean in place chemical exposure on dairy equipment. (Prior materials: Bronze, Stainless Steel)
Rollers:
Guide rollers machined from AcetronŽ GP rod operate smoothly and reliably in lift gate systems used to load cargo onto truck beds. (Prior materials: Cast Iron, Cast Aluminum)
Engineering Notes:
In general, acetals do not perform as well in abrasive wear applications as nylons. Compensation for moisture related growth generally allows NylatronŽ nylons to be used for wet, abrasive applications. If your application requires dimensional consistency in an abrasive, high humidity or submerged environment, ErtalyteŽ PET-P will often offer improved performance.
