Market overview

Epichlorohydrin (ECH, CAS 106-89-8) is made from propylene or glycerine with chlorine and is the key building block for epoxy resins, as well as water-treatment polymers, paper wet-strength resins and synthetic glycerine. Olin is one of the world’s largest ECH and epoxy producers, so the OlinHuntsman merger directly changes this market’s structure.

Key figures at a glance
– Epichlorohydrin market: USD 3.18 bn (2025) to USD 5.85 bn by 2035 at 6.29% CAGR; epoxy resins about 75% of revenue; Asia-Pacific about 45% (Spherical Insights)
– Key producers named include Olin, Solvay, Sumitomo Chemical, Aditya Birla, Formosa, Hexion and Hanwha (Spherical Insights)

Recent developments among key stakeholders
– Jun 2026: Huntsman and Olin signed an all-stock merger of equals (OlinHuntsman, about USD 12.5 bn pro forma revenue, >USD 400 mn synergies); shareholders approved it and closing is expected in 1H 2027 (ChemXplore)

What this means for the market
The merger combines two large positions in this value chain. Integration teams, competitors and customers will reassess capacity, pricing and supplier concentration through the 2027 closing.

How published estimates compare
Published estimates do not distinguish propylene-based from glycerine-based ECH, whose costs and carbon footprints differ widely. Market Krystal sizes both routes, maps chlorine integration and models how the merger changes epoxy-chain supply.

What this report delivers
Annual volume (tonnes) and value (USD) for 2026-2035, segmented by route: propylene (allyl chloride) vs. glycerine (GTE); application: epoxy resins, water treatment, paper chemicals, elastomers, synthetic glycerine; region: China, Europe, North America, India, rest of Asia. Each segment is backed by a producer capacity table, price benchmarks for 2020-2025 by grade and region, trade-flow analysis and a supplier risk map. Companies assessed include Olin, Solvay, Aditya Birla Chemicals, Formosa Plastics, Hanwha Solutions, Sumitomo Chemical, Shandong Haili. The 2036-2047 outlook uses three explicit scenarios (base, constrained supply and technology transition) rather than a single extrapolated curve.

Methodology and transparency
Every third-party figure in this report is cited to its source. Market Krystal estimates are labelled as such, with the volume, price and share assumptions behind them shown in the supporting Excel model, so buyers can audit and adjust them. Where public sources conflict, the report shows the range and explains which evidence it relies on.

The purchased delivery includes the PDF report, Excel datasets and customization around the buyer’s priority region, company set, application or commercial question.
