NASA's Shared Services Center has issued a Special Notice for a sole source procurement of HFA X50 membrane materials for membrane evaporator development at Johnson Space Center. The procurement seeks 3 units of HFA X50 membrane materials (Legacy Part No. 70-2013-5200-4), each measuring 215.29 inches long, from the sole provider Solventum US LLC located in Charlotte, North Carolina. These specialized membrane materials have been historically utilized in spacesuits and the International Space Station's thermal control systems, where they facilitate water evaporation for cooling purposes. The procurement falls under NAICS code 339113 (Surgical Appliance and Supplies Manufacturing) and is classified as miscellaneous service and trade equipment. The performance period extends from July 1, 2025, through September 9, 2025.

The primary purpose of this Special Notice is to inform the contracting community of NASA's intent to award a sole source contract under FAR 13.106-1(b)(1)(i), while providing an opportunity for other organizations to demonstrate their capabilities. Interested organizations must submit their capabilities and qualifications in writing to the primary point of contact, Cara Craft, no later than 1:00 p.m. Central Standard Time on July 7, 2025. Oral communications are not acceptable for this procurement, and all submissions must be in writing. The government will evaluate these capability statements solely to determine whether the procurement should be conducted on a competitive basis, though the final decision remains at the government's discretion. This acquisition supports NASA's ongoing space technology development efforts, specifically for advanced thermal management systems used in space exploration missions.
