In 1979, Evonik launched the thermoplastic elastomer polyether block amide (PEBA) under the brand name Vestamid E from its largest global production site in the Marl Chemical Park. Whether in sports equipment, hydraulic pressure lines in trucks, medical devices or 3D printed high-tech parts, these polyamide 12 elastomers kept finding their way into new demanding applications over the past four decades. Right from the beginning, the polymer has stood out for its excellent low-temperature impact resistance, chemical resistance, high elasticity and good resilience. It was easy to process, dye or over-mold. From the beginning, the TPE offered a uniquely balanced property profile that enabled design-free implementation of demanding applications.
