Acetal Homopolymer (Delrin®) Rod

Acetal Homopolymer (Delrin®) Rod

Acetal homopolymer (also known as Delrin®) rod is a strong rigid plastic with a higher mechanical strength, hardness and creep resistance than acetal copolymer. It also has a high resistance to wear. It is easy to machine with very good electrical insulation properties and is resistant to dilute acids, cleaning agents and some solvents. Acetal homopolymer has a lower thermal expansion rate than acetal copolymer.


Friction bearings, gears, housing parts, rollers, insulators and snap fit connectors.
