UNSPSC 13101705: Styrene butadiene SBR

UNSPSC 13101705 Styrene butadiene SBR is a Commodity code that describes synthetic rubber polymers used primarily in pavement joint and crack sealant formulations for roadway maintenance and repair. State and local governments procure this material as a component in pre-manufactured sealant products (such as polyurethane or silicone-based crack sealants) rather than as a raw material input, with recent activity concentrated in municipal public works departments and state transportation agencies conducting routine pavement preservation and infrastructure rehabilitation.

Recent solicitations show municipal and county transportation departments issuing IFBs and ITBs for ready-to-use crack sealant products and joint sealing systems. The City of San Antonio Finance Department issued IFB 6100019897 on October 15, 2026, for PolyFlex Type 3 crack sealant meeting Texas DOT specifications, with bids due October 16, 2026, for a three-year supply contract with renewal options. The Texas Department of Transportation Lubbock District issued IFB 601340000066820 on August 7, 2026, for silicone joint sealant (Sikasil 728 RCS) and caulking guns, with responses due August 14, 2026. The State of Maine Department of Administrative and Financial Services issued RFQ 17A26041300000000000259 on July 1, 2026, for deck sealants and epoxy polymer concrete overlay systems with quotations due July 15, 2026, establishing a master agreement for statewide agency purchasing. Illinois Department of Transportation District 5 initiated emergency procurement for hot poured joint sealant with a June 10, 2026 deadline. Activity clusters in Texas (San Antonio, Lubbock, Collin County) and extends to Maine and Illinois, with additional pavement rehabilitation work in Santa Clara County, California and Georgia reflecting broader infrastructure maintenance spending. Municipal and county public works departments dominate the issuing-body mix, with state transportation agencies appearing as secondary buyers. Larger infrastructure projects such as Santa Clara County's Central Expressway Pavement Rehabilitation (ITB-RDA-FY26-0694, due May 21, 2026) and Vasona Lake County Park East Trail Reconstruction (ITB-PRC-FY27-0091, due October 7, 2026) bundle sealant work within comprehensive pavement contracts rather than procuring sealants separately, indicating that standalone sealant volume opportunities remain modest relative to integrated repair and rehabilitation contracts where SBR-containing products serve as line items.
