Material Innovation Enables Advanced Biologics Auto-Injector
The biologics market is shifting toward higher-volume medication delivery systems to reduce injection frequency and enable home treatment. Savicred needed to develop a 2.25ml biologics injector that could reliably handle larger volumes and more viscous formulations while ensuring patient safety and ease of use. This required biocompatible materials that could meet stringent performance requirements without compromising manufacturability.
The advanced drug delivery systems space presents tremendous opportunities for innovation as the industry moves toward more complex biologics and patient-friendly drug delivery. As a leading provider of innovative medical materials, we enable manufacturers to develop more advanced, reliable auto-injector solutions that ultimately improve the treatment experience for patients.
Developing auto-injector solutions for high-volume biologics delivery presents complex design and material challenges. This meant addressing multiple critical requirements at the same time: maintaining strength in load-bearing components under injection forces, achieving structural integrity in ultra-thin walls (≤1.0mm) to enable compact design, providing clear visibility of the drug solution, and meeting strict biocompatibility requirements for patient safety, all while supporting efficient manufacturing of complex components.
Our high-performance, biocompatible medical materials, including Makrolon® 2458, enable the part strength, structural integrity, and dimensional stability of auto injectors – ensuring accurate dosing and easy handling for better patient compliance. Their unique combination of properties enables strong yet compact designs with ultra-thin walls, while the exceptional clarity of our polycarbonates allows complete visibility of the drug solution, a critical feature for patient safety and compliance. These innovative medical materials also offer superior processability that enables efficient manufacturing of complex components, allowing Savicred to develop a 2.25ml biologics delivery device that meets the growing demand for high-volume administration of biologics while supporting patient self-administration.

As we push the frontiers of biologics delivery, material innovation is pivotal. The solutions from Covestro provide the durability, consistency, and safety we need to develop biologics auto-injectors that can enhance patient convenience and support treatment adherence at home. Our partnership demonstrates how material innovation can advance medication delivery systems.
