“Covestro’s solutions provide the durability, consistency, and safety we need to develop devices that offer patients more convenient home treatment solutions and enhance their quality of life,” commented Xiao Lin, CEO at Savicred.

High-performance demand on biologics delivery

Driven by demands for reduced injection frequency and enhanced home treatment options, the shift toward high-volume biologics delivery presents complex material science challenges. These devices must manage higher internal pressures and more viscous drug formulations while maintaining precise performance throughout their lifecycle.

This requires materials that can deliver exceptional mechanical strength for structural integrity, dimensional stability for consistent dosing, and proven biocompatibility for patient safety—all while supporting efficient, scalable manufacturing processes.

Covestro’s material technologies are engineered to address these demanding requirements.

Its medical-grade Makrolon polycarbonates (PC) combine high mechanical strength for reliable delivery of larger volumes with outstanding dimensional stability that ensures precise component fit and reliable performance in various storage and usage conditions.

These materials also offer proven biocompatibility for patient safety, while their superior processability enables high-precision molding for complex device components.

This comprehensive performance profile enables device manufacturers to scale up innovation confidently while maintaining safety and reliability.
