The most common engineering nylons are PA6 and PA66. Nylon stock shapes are produced by either extrusion or casting. The process is in part a determinant of the nylon properties of the end product. Modifiers are added to enhance desirable characteristics.
Advantages:
Nylon Rod and Nylon Sheet are tough, durable, general purpose engineering material with special grades for specialty applications. Typical application conditions would be medium speed and temperature in a rugged, abrasive, impact and high load environment.
Disadvantages:
Poor dimension stability, electrical and mechanical properties, may become affected by absorbing moisture or water, acidproof ability not good, can’t dye with acid or touch overmuch acid, weak lightfastness, low endurance in pollution
