Cryogenic mill
Waiver type - Procurement: Nonavailability
Agency: NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (1341) • Product Service Code (PSC) : 6640 | Last Modified: 12/17/2024
Procurement Summary
The U.S. Department of Commerce, National Institute of Standards and Technology, Materials Measurement Laboratory, Materials Measurement Science Division (MMSD) requires a cryogenic mill for grinding plastic materials. The mill must have cryogenic capability to freeze plastics below their glass transition temperature (Tg), making them brittle and suitable for milling into fine particles. MMSD aims to produce and recover submicron (≤ 1 μm) particles, which is achievable only through cryogenic ball milling. This method employs high-impact forces to fracture frozen materials, with liquid nitrogen often used to maintain sub-Tg temperatures and prevent heating during milling.
Waiver Rationale Summary
Based on the findings, it has been determined that a cryogenic mill meeting the MMSD’s requirements is neither mined, produced, nor manufactured in the United States in sufficient and reasonably available commercial quantities and satisfactory quality. Consequently, the Retsch cryogenic mill will be treated as a domestic article for this procurement.
