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.
