Unsaturated Polyester Resin (UPR) Market: 2025 Review

Written by Sam Uctas | Dec 15, 2025 2:31:07 PM

The global UPR market in 2025 was characterized by subdued demand, declining feedstock costs, and increasing competitive intensity. Across North America, Europe, and China, buyers maintained conservative procurement strategies, operating rates remained low to moderate, and producers continued to face persistent margin pressure. While the drivers varied by region, the overarching theme was clear: 2025 brought little demand growth and instead tested the resilience of producers worldwide.

North America: A Year of Stagnation, Soft Demand, and Lingering Uncertainty

Market Overview

The North American UPR market spent most of 2025 in a relatively healthy yet stagnant state. The slow start in January, defined by tentative restocking and isolated areas of strength, ultimately set the tone for the entire year. Downstream demand was stable but uninspired across nearly all sectors.

Demand Recap: Flat and Stable

  • Construction and infrastructure failed to gain traction as high interest rates, affordability concerns, and tariff uncertainty weighed on confidence.
  • The marine and RV sectors experienced a brief surge in momentum in March before reverting to stagnation.
  • Electrical applications stood out as a rare late-year bright spot, offering modest support in Q3 and Q4.

By mid-year, producers reported volumes 5–8% below those of 2024, with little improvement through October and November. The year closed with typical seasonal slowing, consistent with historical norms.

Feedstocks and Pricing: A Gradual Drift Downward

Feedstock trends were steady, predictable, and generally soft:

  • Styrene experienced multiple small downward settlements amid weak benzene and low derivative pull.
  • Maleic anhydride was readily available—at times overly so—with widening discounts.
  • Phthalic anhydride tracked orthoxylene month-to-month.

UPR pricing reflected these fundamentals:

  • Mild price increases in early Q1
  • Progressive softening through the second half
  • Slight year-on-year declines by November, firmly tied to feedstock weakness

End-of-Year Tone

The story for 2025 in North America is one of stagnation rather than distress. Volumes lagged, and visibility remained limited, yet no significant structural deterioration was observed. Sentiment for 2026 is muted but cautiously hopeful, hinging on macroeconomic stabilization and reduced tariff noise.

Europe: Weak Demand, Fierce Competition, and Margin Erosion

Market Overview

While North America experienced stagnation, Europe faced prolonged contraction. Throughout 2025, European UPR producers struggled against lacklustre demand, growing import pressure, and persistent margin compression.

Demand: No Real Recovery Throughout the Year

Construction, automotive, marine, and infrastructure sectors underperformed:

  • Q1 volumes fell early and stayed low.
  • Q2 and Q3 saw little improvement, with volumes down 10–15% year-over-year for many producers.
  • Full-year volumes are expected to finish ~10% below 2024 and 20–25% below 2021's peak, highlighting the sector's structural downturn.

Competitive Landscape: Import Pressure Intensifies

2025 saw a surge in overseas competition:

  • Turkish imports—increasingly dominant—were offered at €950–1300/ton, well below traditional European levels.
  • Chinese resin expanded its presence, especially in composite stone markets, with potential to spill into broader applications.

The result was a price battle European producers rarely won, leading to lower operating rates, worsening margins, and deeply cautious sentiment.

Feedstocks: Soft to Tumultuous

  • Styrene trended downward most of the year, both a relief and a reflection of weak derivative demand.
  • Maleic anhydride repeatedly softened as Asia-origin offers undercut domestic supply.
  • Phthalic anhydride tracked orthoxylene while facing rising exposure to competitive imports.

UPR prices softened gradually, largely because there was little room left for further reductions. Producers attempted to preserve their margins even as costs rose.

Year-End Sentiment

Outlook for 2026 remains deeply cautious. Geopolitical instability, weak industrial activity, and overwhelming import pressure continue to cloud recovery prospects. Some market participants speculate that geopolitical resolutions (e.g., the Russia–Ukraine conflict) could eventually boost demand, although such scenarios remain uncertain and distant.

China: Oversupply, Weak Demand, and Falling Costs Define 2025

Market Overview

China's UPR market in 2025 was shaped by oversupply, weakening domestic consumption, and a steady decline in feedstock costs. Early-year stability gave way to deterioration as new capacity came online, downstream demand underperformed, and crude oil slumped.

Demand Conditions: Brief Stability, Then Broad Weakness

  • January and February were slow due to the Lunar New Year and minimal post-holiday restocking.
  • March–April brought a tentative improvement, which was quickly undone by feedstock volatility and geopolitical shocks.
  • Throughout summer and autumn, the construction, sheet moulding, and consumer goods sectors operated with minimal restocking and high demand for purchasing.

By Q4, operating rates hovered between 29% and 37%, extremely low and highly sensitive to small order shifts.

Feedstocks: Continuous Erosion

Styrene, maleic anhydride (MA), and phthalic anhydride (PA) all declined significantly:

  • Styrene dropped sharply multiple times due to oversupply and high port inventories.
  • MA weakened dramatically as new capacity pushed many producers into negative margins.
  • PA trended steadily lower, limited only by firmer-than-expected costs and low inventories.

Intermittent mid-month rebounds—typically tied to fluctuations in crude oil—provided little lasting support.

Pricing Trends

UPR pricing followed feedstocks lower:

  • Declines accelerated in August, September, and October
  • By November, general-purpose resin prices had fallen to RMB 7,600–8,400/ton, among the year's lowest

Despite weak resin prices, margins were still pressured because feedstocks occasionally rebounded when UPR demand did not.

Supply Dynamics: New Capacity Reshapes the Market

Two significant developments defined 2025:

  1. Hanyu New Materials started up 165 kt/year in October
  2. Fangxin Resin prepared to launch 250 kt/year (Phase I) in late Q4

With exports rising nearly 16% year-over-year from January to May, China increasingly relied on overseas markets as domestic oversupply intensified.

End-of-Year Outlook

Sentiment entering Q4 was subdued and cautious. With crude oil at annual lows, limited demand recovery expected during winter, and new capacity coming online, the near-term trend remains biased downward. High competition, discounting, and low margins are expected to persist into early 2026.
