PA46
PA46 (Polyamide 46) is a highly crystalline aliphatic polyamide produced by polycondensation of 1,4-butanediamine and adipic acid, with a melting point of 295°C. It combines very high crystallinity with extremely fast crystallization rate. PA46 retains mechanical properties at elevated temperatures far better than PA6 and PA66, making it ideal for friction-driven engineering components such as gears and chain guides.
