Nylon - Polyamide (PA)

The plastic for dynamic applications

Nylon is the plastic used for dynamic applications in mechanical engineering due to its high wear resistance in combination with good sliding and rolling properties. The hard material has a strong sound damping capacity, is tough and stiff and has good machining capabilities.

By adding fillers, Nylonis produced in many versions, greatly improving various properties. For example, Nylon filled with oil provides integral lubrication in dynamic applications, resulting in lower friction and therefore longer service life.

Other names and trade names for Nylon are Nylon 6, Nylon 6 GOL and Nylon 66.

How to identify Nylon

Nylon is the well-known product name for Polyamide (PA). The material is standard available in natural (with a yellowish glow) and black. Due to the specific gravity of 1.14 grams per cubic centimetre, Nylon sinks.

Nylon is hard and robust. Due to its stiffness, the material cannot be bent properly. When processed, Nylon shows long chips.

The technical properties of Nylon

Nylon is the well-known product name for the plastic polyamide, abbreviated PA.

Due to good sliding and rolling properties, Nylon is extremely suitable for moving parts. Think of gears, plain bearings or cable discs.

Nylon is tough and robust, so it doesn't break easily under heavy loads. Nylon is resistant to many chemicals including oil, grease and gasoline. Certain types of nylon are suitable for the food industry.

Furthermore, it has a high moisture absorption, which means that it is usually less dimensionally stable.
