Better performing IV connector with Covestro polycarbonate

Better performing IV connectors with Makrolon® polycarbonate

The right choice for oncology drug delivery

Approximately 40 percent of people will be diagnosed with cancer in their lifetime. During treatment, everything must work as designed, down to the plastic used in IV connectors.


An IV connector formed from Makrolon® Rx3440 polycarbonate from Covestro offers superior durability and oncology drug resistance.

Task

Some cancer drugs contain aggressive solvents - these solvents dissolve, or attack, the plastic materials used in luers and other IV connectors that help deliver oncology drugs. To prevent part damage, a medical OEM sought a plastic material with increased chemical resistance for its luer connector.

Challenge

The selected material needed to have increased oncology drug resistance to address attacks from solvents including benzyl alcohol and dimethyl acetamide that can result in cracking or damage. The OEM also needed a material that could be utilized with minimal validation and requalification.

Solution

Makrolon® Rx3440 polycarbonate was selected for the luer connector due to its oncology drug resistance. Compared to transparent competitive materials, this material also demonstrated the best retention of stress and best overall combination of physical properties. A Covestro-designed novel testing apparatus was used to test the luer connector against oncology simulants and a common disinfectant, enabling immersion testing under real-life loading to prove its chemical resistance and toughness.
