Polyamide 6/6 - Nylon 6/6 - PA 6/6 Super-Tough

May 16 2001

Polymer Type

Thermoplastic

Advantages

Superior impact properties and very low notch sensitivity compared with other engineering thermoplastics. Short moulding cycles therefore higher productivity. Good chemical resistance. Good surface finish.

Disadvantages

Low flexural modulus and maximum operating temperature when compared with unmodified PA 6/6.
