ABS vs Acetal gears





January 10, 2012

Q. Hello,
My name is Mick. I really need to know the benefits of using Acetal rather than ABS. We are about to market a product that uses Acetal for the gears rather than ABS. I am in sales and do not know ANYTHING about these two substances.

Thank You for your help

A. Acetal (also called polyoxymethylene or POM) is a semi-crystalline polymer, as are nylons and polyesters. ABS is an amorphous polymer, with polycarbonate and acrylic (PMMA) being other examples. In general, semi-crystalline polymers possess better creep resistance, fatigue strength, wear resistance and solvent resistance than amorphous polymers. This is why highly stressed plastic components like gears bearings typically use semi-crystalline polymers.
