NYLON unfilled is one of the oldest and most widely used engineered mechanical plastics. Its combination of toughness, dimensional stability, wear resistance, availability, and versatility make it a natural choice for informed engineers looking to improve their project. NYLON has served well in replacing many metals and offers a design choice when noise reduction and long life are important. Originally only available in blue, now cast NYLON is also available in natural and black. Performance improving fillers, depending on the particular application are also available.
