Nylon 66 material for machining has improved temperature resistance and lower rates of water absorption when compared to standard nylon 6.

The reason behind choosing polyamide over other materials will vary for different applications. When using polyamide for electrical cable protection, it offers better performance, flexibility, and impact resistance than PVC protection. In the automotive industry, it is used because it is cheaper and lighter than metal. In machines, it is used over other materials due to its high flexibility and durability.
