UNSPSC 12162008: Prepolymers

A monomer or system of monomers that have been reacted to an intermediate molecular weight state; also known as Polymer Precursors.

UNSPSC 12162008 Prepolymers (Commodity) covers emulsified and conditioning polymers that state and local water and wastewater authorities procure for biosolids and sludge dewatering operations at treatment plants. These polymers are applied in centrifuges, belt filter presses, and screw presses to increase cake solids content and separation efficiency during solids conditioning. The issuing bodies are typically independent water and wastewater special districts and state environmental service agencies, with recent activity concentrated among regional water authorities serving multiple counties and state-level procurement entities managing multi-facility systems.

Recent opportunities show active procurement across Florida and Maryland. The Tohopekaliga Water Authority (Toho), an independent special district serving portions of Osceola, Orange, and Polk counties in Florida, posted IFB-26-011 on February 23, 2026, due March 26, 2026, for supply and delivery of emulsified polymer across five water reclamation facilities with approximately 50,020 wet tons of annual sludge processing; the IFB required mandatory bench testing at the South Bermuda facility on March 10-12, 2026, with polymers evaluated on 18 percent cake solids and 84 percent solids capture efficiency. The Maryland Environmental Service posted a Small Business Reserve procurement (Solicitation 1262645) on May 14, 2026, due June 15, 2026, for furnish and delivery of liquid emulsion polymer at the Freedom Wastewater Treatment Plant in Carroll County, Maryland, seeking approximately 32,200 pounds per year over a five-year contract with mandatory jar testing by June 8, 2026 and full-scale dewatering trials demonstrating minimum 19 percent total solids content. Both solicitations require detailed technical data, safety data sheets, and references from similar municipal wastewater treatment plant contracts.
