Biomaterials for medical devices

Shaping the future of medical device innovation with next-generation biomaterials

Evonik offers a broad portfolio of biomaterials for medical devices that meet the highest standards of biocompatibility, biostability, and performance. Our biomaterials support innovation in medical devices, from short-term to long-term implantable devices, while our bioresorbable medical polymers enable controlled degradation, opening further possibilities for medical device applications.

The role of biomaterials in medical devices

Biomaterials are the foundation of safe and effective medical devices. These materials must interact with the human body without causing adverse reactions, making biocompatibility a critical requirement. Evonik’s biomaterials are engineered to be non-toxic, non-immunogenic, and compliant with stringent regulatory standards. Equally important is biostability—the ability of a material to maintain its integrity and functionality over time within the body. 

Evonik’s expertise in advanced biomaterials

With decades of experience in polymer science and medical-grade material development, Evonik is a trusted partner to the global medical device industry. We offer a comprehensive range of high-performance biomaterials, including RESOMER®, VESTAKEEP®, and VECOLLAN®, each tailored to specific medical applications. Our team supports customers with customization, regulatory guidance, and global technical support, helping accelerate product development from concept to market.

Bioresorbable biomaterials are designed to safely degrade within the body after fulfilling their function, eliminating the need for surgical removal. These materials are ideal for temporary implants such as sutures, orthopedic pins, and drug delivery systems. Evonik’s RESOMER® range offers a wide range of bioresorbable polymers with tunable degradation rates and mechanical properties. Our VECOLLAN® recombinant collagen-based biomaterial further expands the possibilities for natural, bioresorbable solutions in regenerative medicine and wound healing.

Materials intended for short-term body contact—typically up to 30 days—must meet specific regulatory and performance criteria. Evonik offers a range of materials for applications such as catheters, wound care products, and surgical tools. Our care-grade polymers, including VESTAKEEP®, TROGAMID®, and VESTAMID®, are tailored for short-term use. For wound care and medical aesthetics, epicite® provides advanced healing properties, while ENDEXO® surface modification technology enhances the hemocompatibility of medical devices, reducing thrombosis and biofouling.

Devices that remain in the body for more than 30 days require materials with exceptional biostability, mechanical strength, and safety. Evonik’s portfolio includes VESTAKEEP®, DEGACRYL®, and DEGAPLAST®, which perform reliably in long-term implantable applications such as orthopedic devices, stents, and spinal implants. These materials are tested for durability and resistance to physiological stress, ensuring consistent performance over the life of the device.
