The Department of Defense, specifically the Naval Surface Warfare Center (NSWC) Indian Head Division, intends to award a sole-source contract to Mach I, Inc. for the procurement of Glycidal Azide Polymer (GAP-5527) resin and Glycidal Azide Polymer Plasticizer (GAP-0700 Plasticizer). This procurement is essential to support a new research and development effort involving propellant ingredients, as Mach I Chemicals is the only known source capable of meeting the government's specific requirements for these energetic materials. Interested vendors must respond by 3:30 p.m. EST on October 3, 2024, and should direct their inquiries and documentation to Sharon Cooper via email at sharon.cooper@navy.mil, ensuring they are registered in the System for Award Management (SAM) at http://www.sam.gov.
