Dry MoS2 Filled PA 6
Dry molybdenum disulfide PA 6 is a grade of PA 6. The graph bars on the material properties cards below compare dry molybdenum disulfide PA 6 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.
