Polyamide 66 has excellent flow compared to many other engineering plastics, and it is possible to manufacture quite thin walled parts with these materials. The graphs below give the viscosity versus shear rate curves of Polynil P50L, Polynil P50FI, Nilamid A3 H2 G5, Nilamid A3 H2 G7 and Nilamid A3 H2 G10.
