UNSPSC 13101716: Synthetic polyisoprene IR

UNSPSC 13101716 Synthetic polyisoprene IR is a Commodity code that frames products state and local governments buy as materials for asphalt pavement repair and joint sealing—specifically crack sealants, joint sealers, and related pavement-maintenance compounds deployed in road, parking lot, and airfield rehabilitation work. Recent solicitations show this code tagged to crack-sealant procurements, joint-sealer bids, and pavement-repair projects that call for synthetic rubber or elastomer-based sealant products meeting Department of Transportation specifications. The buying base spans city public-works departments, county transportation and procurement offices, state departments of transportation, and airport authorities. City of San Antonio Finance Department (Public Works), County of Santa Clara Procurement Department, Texas Department of Transportation Lubbock District, and the State of Illinois Department of Transportation are among recent repeat issuers under or near this code.

Geographic activity concentrates in Texas, California, and the upper Midwest, with secondary activity in the Northeast and Southeast.
