Thermosetting unsaturated polyester resin refers to a synthetic polymer material that undergoes irreversible curing through chemical cross-linking to form a rigid and durable structure. It is produced through the reaction of unsaturated polyester polymers with reactive monomers, providing properties such as strength, corrosion resistance, and dimensional stability. These resins are widely used as high-performance materials in industrial applications requiring lightweight, durable, and heat-resistant solutions.
The primary types of thermosetting unsaturated polyester resin include orthophthalic unsaturated polyester resin, isophthalic unsaturated polyester resin, terephthalic unsaturated polyester resin, dicyclopentadiene unsaturated polyester resin, and other types. Orthophthalic unsaturated polyester resin refers to a widely used thermosetting resin produced from orthophthalic anhydride and other reactive components, offering good mechanical strength, chemical resistance, and processability. These resins are available as liquid resin, powder resin, bulk molding compounds, and sheet molding compounds. They are produced using bulk polymerization, solution polymerization, suspension polymerization, and emulsion polymerization and serve end-user industries including aerospace, automotive, construction, electrical and electronics, marine, industrial equipment, consumer goods, renewable energy, and others.
Tariffs are influencing the thermosetting unsaturated polyester resin market by increasing the cost of imported polyester raw materials, reactive monomers, chemical additives, fillers, and resin-processing equipment required for production. This is increasing manufacturing costs and affecting construction, automotive, electrical and electronics, marine, aerospace, and renewable energy applications, particularly in regions dependent on imported chemical materials such as Asia-Pacific and Europe. Raw material-intensive and specialty resin segments are most affected due to global chemical supply chain dependencies. However, tariffs are also encouraging domestic resin production, regional supplier diversification, localized manufacturing, and investment in bio-based and low-emission polyester resin technologies, improving long-term supply chain resilience.

This thermosetting unsaturated polyester resin market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The thermosetting unsaturated polyester resin market size has grown strongly in recent years. It will grow from $7.2 billion in 2025 to $7.64 billion in 2026 at a compound annual growth rate (CAGR) of 6.0%. The growth in the historic period can be attributed to increasing demand for lightweight composite materials, growing use of unsaturated polyester resins in construction applications, rising demand for corrosion-resistant materials, expanding automotive composite component production, increasing adoption of durable fiberglass-reinforced materials.
The thermosetting unsaturated polyester resin market size is expected to see strong growth in the next few years. It will grow to $9.49 billion in 2030 at a compound annual growth rate (CAGR) of 5.6%. The growth in the forecast period can be attributed to growing demand for bio-based unsaturated polyester resins, rising adoption of lightweight composites in electric vehicles, increasing demand for low-emission resin formulations, growing use of advanced polyester resins in renewable energy equipment, and expanding demand for high-performance composite materials. Major trends in the forecast period include increasing adoption of low-styrene emission polyester resins, growing demand for corrosion-resistant polyester resins, rising development of bio-based unsaturated polyester resins, increasing use of low-shrink polyester resins, and growing demand for high-temperature resistant polyester resins.
The rapid growth in construction is expected to propel the growth of the thermosetting unsaturated polyester resin market in the coming years. Construction refers to the process of building, renovating, or expanding residential, commercial, industrial, and infrastructure facilities using various materials and engineering techniques. The rapid growth in construction is primarily driven by increasing urbanization, which is creating greater demand for residential, commercial, and infrastructure development. Thermosetting unsaturated polyester resins support the construction industry by offering lightweight, durable, corrosion-resistant, and high-strength composite materials used in roofing panels, pipes, tanks, sanitary ware, structural components, and architectural applications. For instance, in February 2026, according to the Office for National Statistics, a UK-based government department, the value of new construction work in Great Britain increased by 1.4% in 2024 to a record $189.01 billion (£140.7 billion), while annual construction new orders increased by 5.6% to $96.32 billion (£71.7 billion). Therefore, the rapid growth in construction is driving the growth of the thermosetting unsaturated polyester resin market.
Major companies operating in the thermosetting unsaturated polyester resin market are focusing on developing advanced solutions, such as bio-based unsaturated polyester resins, to reduce reliance on fossil-based raw materials and enhance sustainability in composite applications. Bio-based unsaturated polyester resins are unsaturated polyester resins produced wholly or partially from renewable biological feedstocks, including plant-based oils, sugars, or biomass-derived chemicals, rather than conventional petroleum-based raw materials. For instance, in May 2025, Bowden Chemicals, a UK-based specialty chemical company, secured a government SMART grant to develop a bio-based unsaturated polyester resin. This innovative resin technology is intended to incorporate renewable materials into unsaturated polyester resin formulations, providing a more sustainable alternative to conventional petroleum-derived thermosetting resins. The development focuses on retaining the performance characteristics of traditional UPR systems, including strength, durability, and compatibility with composite manufacturing processes, while reducing carbon footprint and addressing the growing demand for environmentally responsible materials across industries such as automotive, construction, and marine composites.
In November 2024, Nippon Paint Holdings Co. Ltd., a Japan-based coatings and chemicals company, acquired AOC for €2.1 billion ($2.3 billion). Through this acquisition, Nippon Paint aims to reinforce its position in the global composites and specialty materials industry, broaden its resin technology portfolio, and strengthen its capabilities in high-performance coating and composite applications. AOC Resins LLC is a Switzerland-headquartered manufacturer of specialty resin formulations, including unsaturated polyester, vinyl ester, alkyd, and other resins used in composites, coatings, adhesives, and specialty applications.
