Conditioned PA 6/12
Conditioned PA 6/12 is a grade of PA 6/12. The graph bars on the material properties cards below compare conditioned PA 6/12 to: polyamide plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
