Compared to other polyamides, Polyamide 4.6 (PA 4.6) is the most fatigue-resistant of all. The thermal dimensional stability is high. PA 4.6 is more chemically stable and crystallizes better than PA 6 and PA 6.6. When other polyamide types do not perform, polyamide 4.6 retains its properties at elevated temperatures. Its applications are similar to other polyamide types and PA 4.6 is used in electronic and electrical components.
