1 6 Hexanediol Hdo Market: Market Size & Forecast 2026

1,6-Hexanediol is a linear diol with hydroxyl groups at each terminal carbon, valued for its role as a reactive intermediate in polymers and specialty resins. The global market is estimated at USD 1.326 billion in 2026, supported by annual volumes in the multi-hundred-thousand metric ton range. Official statistics do not isolate HDO, as agencies such as the US Census Bureau, Eurostat PRODCOM, and UN Comtrack report it within broader categories such as HS Code 290539 for acyclic diols.

Polyurethane consumption remains the dominant pull on HDO, where it functions as a chain extender that improves hardness, flexibility, and chemical resistance in elastomers, foams, and coatings. Tightening environmental standards are accelerating the shift toward waterborne, high-solids, and UV-curable formulations, all of which incorporate HDO-based diacrylates and specialty polyesters. Parallel interest in bio-based adipic acid and hexamethylenediamine from renewable feedstocks is opening alternative supply pathways that could lower long-run costs.

By application, HDO is segmented into polyurethanes (the largest share), coatings and UV-curable resins, polyesters and plasticizers, and adhesives, with smaller volumes going into personal care and pharmaceutical intermediates. By grade, technical-grade HDO dominates volumes while high-purity grades command premium pricing for electronics and life-science uses. Asia-Pacific leads consumption, driven by Chinese and Indian polyurethane and coating manufacturing, followed by Europe where strict environmental rules support specialty applications, and North America where production is concentrated among a few large chemical firms.

What are the recent trends and outlook?

Through 2031, the HDO market is expected to track a mid-single-digit CAGR, supported by sustained polyurethane growth and accelerating coatings innovation. Bio-based production from furfural, levulinic acid, and glycerol-derived feedstocks is moving from pilot to commercial demonstration, which could reshape supply.
