What's driving sentiment this week:
Past Week (2026-06-01 to 2026-06-08) — Sentiment: Mixed
Dow’s announcement on June 5th confirming the shutdown of its Tertre Belgium polyols plant removes approximately 94 kt/year of supply, tightening global polyether polyol availability and exerting strong upward price pressure.
Propylene oxide prices in China surged sharply on June 8th, pushing raw material costs higher and injecting volatility into domestic polyether polyol trading sentiment, creating short-term price spikes but undermining production stability.
Crude oil prices rose 4.32% to $94.45/bbl on June 8th, elevating energy and feedstock costs across petrochemical chains and weighing on polyether polyol margins through higher production expenses.
This Week (2026-06-08 to 2026-06-14) — Outlook: Neutral
Polyether polyol prices face offsetting pressures this week as reduced global supply from Dow’s shutdown battles elevated feedstock and energy costs driven by volatile crude oil and propylene oxide markets.
The EIA Short-Term Energy Outlook release on June 9th stands as the key near-term catalyst, with potential revisions to oil price and supply forecasts that could swing feedstock cost expectations.
A downward revision in global crude oil or propylene oxide cost forecasts would ease cost-driven margin pressure and support more stable polyether polyol pricing dynamics.
Key Market Impact
Tightened polyether polyol supply from Dow’s facility closure currently dominates pricing, but margin compression risk from soaring propylene oxide and crude oil costs caps upside gains.
Producers and buyers are likely to navigate cautious procurement and production schedules, balancing inventory hoarding against margin squeezes amid uncertain feedstock price volatility.
How About the Price?
Price Trajectory 2020–2026 (Brief Recap)
Phase 1 — COVID-19 Demand Shock (2020-01 to 2020-12): The COVID-19 pandemic caused a sharp decline in global polyether polyol demand as major end markets including automotive, construction, and furniture sectors were severely impacted; prices fell from $1100 in January to a low of $950 in October 2020.
Phase 2 — Post-COVID Recovery and Steady Rise (2021-01 to 2022-12): Post-COVID recovery led to a steady uptick in demand supported by rebounds in construction and automotive sectors; prices rose consistently from $1100 in January 2021 to $2250 in December 2022.
Phase 3 — Capacity Expansion Amid Continued Demand Growth (2023-01 to 2024-09): Capacity expansions by Dow Chemicals in Freeport and MCNS in South Korea supported growing demand, with prices escalating from $2300 in January 2023 to $3300 by September 2024 despite rising supply.
Phase 4 — Capacity Reductions and Planned Closures (2024-10 to 2025-12): Dow’s plant shutdowns in Argentina and announced closure of its Belgium polyether polyols facility amid oversupply exerted supply restraint; prices continued incremental gains from $3350 in October 2024 to $3750 in June 2025.
Phase 5 — Early 2026 Market Softening and Feedstock Volatility (2026-01 to 2026-05): Early 2026 saw softer downstream demand in North America with a 12.4% QoQ price index decline, but China experienced a surge due to soaring propylene oxide costs and supply uncertainty; price data ends in May 2026 with incremental increases from $4100 in January to $4300 in May.
Supply-side factors
- Dow Chemicals completed a 250,000 metric ton/year expansion of its propylene oxide-polyether polyol complex in Freeport, Texas (2023-01 to 2023-12).
- MCNS expanded its polyol production plant in Ulsan, South Korea, increasing capacity by 150,000 metric tons annually (2024-01 to 2024-09).
- Dow permanently shut its Argentina polyols plant amid global oversupply (2024-10 to 2024-12).
- Dow disclosed plans to close its 94 ktpa polyether polyols facility in Tertre, Belgium, by March 2026 citing high European energy costs (2025-01 to 2025-12).
Demand-side factors
- COVID-19 pandemic caused sharp decline in global polyether polyol demand impacting automotive, construction, and furniture sectors (2020-01 to 2020-12).
- Post-COVID recovery boosted polyether polyol demand driven by global construction and automotive sector rebound (2021-01 to 2022-12).
- Early 2026 saw softer downstream demand conditions reflected in North America Polyol Price Index falling 12.4% QoQ (2026-01 to 2026-02).
Substitutes & Alternatives
| Substitute / Alternative | Replacement Scenario / How It Substitutes |
|---|---|
| Polyester Polyol | Direct functional substitute for polyether polyol in polyurethane systems. Used in CASE applications (coatings, adhesives, sealants, elastomers) and rigid foams where superior hydrolytic stability under dry conditions, higher tensile strength, and better solvent resistance are needed. Requires no reformulation of the isocyanate side; the polyol is simply swapped, though processing conditions (viscosity, reactivity) must be adjusted. Less preferred in flexible slabstock foam due to higher cost and hydrolysis susceptibility in humid environments. |
| Polycarbonate Polyol | Replaces polyether polyol in high-performance elastomers, TPU, and coatings where exceptional hydrolysis resistance, UV stability, and mechanical durability are required (e.g., automotive, medical devices). Drop-in replacement at the formulation level but at significantly higher cost; typically used only where polyether or polyester polyols cannot meet performance specs. |
| Bio-based Polyols (soy, castor, palm oil-derived) | Partial or full replacement of petroleum-derived polyether polyol in flexible and rigid foams and CASE applications, driven by sustainability mandates. Castor oil (naturally polyfunctional) can be used directly or chemically modified. Soy-based polyols typically replace 10–30% of conventional polyether polyol in slabstock foam formulations. May require reformulation to compensate for differences in OH number, functionality, and viscosity. |
| Polytetramethylene Ether Glycol (PTMEG / PTMG) | Replaces polyether polyol (specifically PPG-based diols) in high-performance spandex fibers, TPU, and elastomers where superior low-temperature flexibility, resilience, and hydrolysis resistance are needed. Used as a drop-in diol in two-component PU systems. Higher cost limits use to specialty applications. |
| Mannich Polyols (amine-initiated rigid foam polyols) | Used as a substitute or partial replacement for standard sucrose/glycerol-initiated polyether polyols in rigid polyurethane and polyisocyanurate (PIR) foam insulation. Mannich polyols provide autocatalytic behavior (reducing amine catalyst loading) and improved fire performance. Substitution is straightforward within rigid foam formulations. |
| Phenolic Resins (for rigid insulation) | In rigid thermal insulation board applications, phenolic foam systems can substitute for polyurethane/polyisocyanurate rigid foam (which uses polyether polyol) where very low lambda values and superior fire performance are required (e.g., building facades). This is a system-level substitution, not a drop-in replacement; the entire chemistry changes. |
| Epoxy Resins | In structural adhesives, coatings, and composite matrices, epoxy systems can substitute for polyurethane systems based on polyether polyol where higher rigidity, chemical resistance, or adhesion to metals is prioritized. Requires complete reformulation; not a drop-in replacement. Common in aerospace, marine, and industrial flooring applications. |
| Silicone Polyols / Silicone Elastomers | In sealants, elastomers, and flexible coatings requiring extreme temperature range (–60 °C to +200 °C), UV stability, and weatherability, silicone-based systems substitute for polyether polyol-based polyurethane sealants and elastomers. Full system change; significantly higher cost. Used in construction glazing, automotive, and electronics. |

Key Influence Events
Polyether polyol is a class of oligomeric or polymeric compounds characterized by a polyether backbone (repeating ether linkages, –C–O–C–) and multiple terminal hydroxyl (–OH) groups. They are produced primarily by the ring-opening polymerization of cyclic ethers—most commonly propylene oxide (PO) and/or ethylene oxide (EO)—onto a low-molecular-weight initiator (starter) molecule such as glycerol, sorbitol, sucrose, or propylene glycol, using an alkaline (KOH) or double-metal cyanide (DMC) catalyst. The resulting polyols range from low-viscosity liquids to waxy solids depending on molecular weight, functionality, and EO/PO ratio. They are the principal reactive component in polyurethane systems, reacting with isocyanates to form flexible foams, rigid foams, elastomers, coatings, adhesives, and sealants. Key commercial parameters include hydroxyl number (OH number), molecular weight, functionality, viscosity, and water content.
