PBA is an engineering polymer notable for its combination of high tensile strength and exceptional elongation at break, making it a tough, impact-resistant material suitable for demanding structural and mechanical applications. It is commonly used in automotive components, industrial fasteners, consumer goods requiring durability, and applications where both stiffness and flexibility are needed to absorb stress without brittle failure. Engineers select PBA over more rigid plastics when impact resistance and deformation tolerance are critical, and over elastomers when significant load-bearing stiffness is required.
