Unsaturated polyester resins market to reach $14.74 billion by 2030

The Business Research Company says the global market for unsaturated synthetic polyester resins is growing on construction, transportation and renewable energy demand. The report projects the market will rise from $11.79 billion in 2026 to $14.74 billion by 2030, with Asia-Pacific leading growth.

Why it matters: - Unsaturated synthetic polyester resins are used in composite materials that need strength, durability and corrosion resistance. - The market’s growth tracks demand from construction, automotive, marine, aerospace and renewable energy uses. - The shift toward bio-based and lower-emissions resin formulations points to a wider materials transition across industrial supply chains.

What happened: - The Business Research Company published its Unsaturated Synthetic Polyester Resins Global Market Report 2026 covering market size, trends and forecasts through 2035. - The report estimates the market will grow from $11.1 billion in 2025 to $11.79 billion in 2026. - The report projects the market will reach $14.74 billion by 2030. - The report places Asia-Pacific as the largest market in 2025 and the fastest-growing region over the forecast period. - The report also covers South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - The company made a free sample available here. - The full report is available here.

The details: - The report says growth in the historical period came from construction demand, fiberglass reinforced plastics in industrial machinery, marine and transportation uses, wind energy production and demand for corrosion-resistant materials. - The report forecasts a 6.2% CAGR from 2025 to 2026. - The report forecasts a 5.8% CAGR from 2026 to 2030. - The report says future demand will be driven by lightweight automotive components, sustainable resin options, renewable energy infrastructure, aerospace composites and high-strength molded products. - The report highlights bio-based unsaturated polyester resin formulations, low styrene emissions and thermosetting resin systems as key trends. - The report defines unsaturated synthetic polyester resins as thermosetting polymers made by polycondensation of unsaturated dicarboxylic acids or anhydrides with diols. - The report says the resins cure with vinyl monomers such as styrene to form a rigid three-dimensional network. - The report says the materials are valued for mechanical strength, chemical resistance and versatility. - The construction sector remains a major end market because these resins are used in reinforced plastics, panels, pipes and coatings. - Eurostat reported in June 2025 that construction production rose 3.0% in the euro area and 2.5% across the EU in April 2025 from a year earlier. - The report’s 2026 edition adds market attractiveness scoring, TAM analysis, company scoring matrix graphics, Excel-based forecasting dashboards, market hotspots infographics, key technology analysis and updated graphics and tables.

Between the lines: - The forecast suggests the market is expanding beyond traditional industrial uses into cleaner and lighter-material applications. - The emphasis on bio-based and low-styrene products signals pressure from both sustainability requirements and emissions concerns. - Asia-Pacific’s lead indicates where manufacturing and infrastructure demand are concentrating most quickly.

What's next: - The market is expected to keep growing as electric mobility, renewable energy buildout and advanced composites increase resin demand. - Product development will likely center on lower-emissions, lighter and more durable formulations. - The report positions the sector for continued expansion through 2030 and beyond, with broader forecast coverage through 2035.
