Duratron™ T4203 PAI AE (aerospace) offers the most superior impact strength of all Duratron™ T PAI grades, while also possessing the highest elongation of all Duratron™ grades. Due to its intrinsic high temperature resistance, dimensional stability and exceptional machinability, Duratron™ T4203 PAI AE is often used for precision parts in high-tech equipment. Its ability to carry high loads over a broad temperature range also makes it ideal for structural components such as linkages and seal rings and an excellent choice for aerospace wear applications involving impact loading and abrasive wear.
