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