One of the fastest-growing segments in the pharmaceutical industry is biologic drugs. Derived from a microorganism, or plant or animal cells, biologics are often used to treat rheumatoid arthritis, cancer, diabetes and many other diseases. Biologics are injected or infused, which typically requires inconvenient visits to specialty healthcare facilities or painful self-injections for patients.


To solve these challenges, Enable Injections, Inc. (, has developed a disposable on-body drug delivery device that allows patients to comfortably self-administer high-volume and/or high-viscosity therapeutics. Components of the Enable device are injection molded with polycarbonate materials from Covestro LLC.


The housing of the on-body device features Makrolon® Rx1805 polycarbonate in a purple tint. Bayblend® M850 XF PC+ABS blend in a white tint is featured on the transfer system, which allows the patient to easily transfer the biologic drug from its original container to the Enable on-body delivery device.


“Covestro supported Enable Injections every step of the way from selecting the right polycarbonate materials to in-house part testing and manufacturing support,” said Brian Faul, business development manager – Midwest region, Polycarbonates, Covestro LLC.


Makrolon® Rx1805 polycarbonate, a medical-grade resin often used to produce transparent parts for medical devices, offers several advantages for the device’s housing including:


• Acceptable for sterilization with high-energy radiation

• Biocompatible according to many ISO 10993-1 test requirements

• High viscosity

• High lipid resistance


Bayblend® M850 XF PC+ABS blend offers several benefits for the transfer system including:


• Biocompatible according to many ISO 10993-1 test requirements

• Good flowability

• Heat resistant up to 131°C (Vicat B/120)

• High dimensional accuracy, stability and toughness


“Biologic medicines are very sensitive and the materials selected for the delivery and transfer systems are of utmost importance for patient safety,” said Lauren Zetts, North America market manager, Medical and Consumer Products –Polycarbonates, Covestro LLC. “At Covestro we continuously strive to provide medical OEMs the materials they need to bring their devices to market, so naturally we’re gratified to be selected for this application, which is making such a positive impact on patients’ lives.”
