Unsaturated Polyester Resin Outlook 2026: Weak Demand and Uneven Regional Pricing

Unsaturated polyester resin markets showed brief seasonal and feedstock-driven strength in H1 2026, but underlying demand remained weak across North America, Europe and China.

Key Takeaways

• The global unsaturated polyester resin (UPR) market entered 2026 with limited momentum.
• Demand remained weak across construction, infrastructure, marine and recreational vehicle applications for most of the first half.
• European demand remained persistently weak across construction, infrastructure, automotive and marine uses.

A Market Still Waiting for a Durable Recovery

The global unsaturated polyester resin (UPR) market entered 2026 with limited momentum. Across major regions, buyers remained cautious, downstream demand was uneven and temporary price increases were driven more by raw-material volatility than by sustained consumption growth.

North America: March Provided Only a Seasonal Lift

Demand remained weak across construction, infrastructure, marine and recreational vehicle applications for most of the first half. March was the strongest month, with volumes reportedly up 10–15% month on month, but the improvement largely reflected seasonal recreational demand rather than a broad recovery. Trade-policy uncertainty encouraged buyers to delay purchasing decisions. Geopolitical disruption also tightened propylene glycol availability and contributed to a sharp cost increase before feedstock conditions stabilized later in the half.

Europe: Lower Volumes and Limited Confidence

European demand remained persistently weak across construction, infrastructure, automotive and marine uses. First-quarter volumes were estimated below already subdued 2025 levels, and second-quarter volumes were expected to finish 5–15% lower year on year. UPR prices increased by around €800 per metric ton during H1 as producers responded to higher feedstock costs, but the market entered the summer with little expectation of a meaningful demand rebound.

China: Feedstock Inflation Gave Way to Oversupply

China experienced two distinct phases. Q1 prices rose as styrene and other feedstocks increased, squeezing producer margins because resin prices could not keep pace. In Q2, easing raw-material costs and weak demand pushed prices lower. Operating rates declined as producers managed poor profitability, while buyers delayed purchases in anticipation of further decreases.

H2 2026 Outlook

North American volumes are likely to remain broadly stable with only gradual improvement. Europe faces a particularly weak summer, especially in marine applications. China is expected to remain oversupplied, with prices rangebound to slightly weaker until downstream demand improves sustainably.
