What Is Covered Under Unsaturated Synthetic Polyester Resins Market?

Unsaturated synthetic polyester resins are a class of thermosetting polymers formed by the polycondensation of unsaturated dicarboxylic acids or anhydrides with diols. These resins contain reactive double bonds that enable cross-linking, typically when cured with a vinyl monomer such as styrene, resulting in a rigid three-dimensional structure. Unsaturated synthetic polyester resins are valued for their mechanical strength, chemical resistance, and ability to be molded into durable composite materials. The main product types of unsaturated synthetic polyester resins include orthophthalic, isophthalic, dicyclopentadiene, and other product types. Orthophthalic refer to general-purpose resin formulations widely used for composite applications due to their good mechanical strength, chemical resistance, and cost effectiveness. These resins are manufactured through processes such as hand lay up, spray up, pultrusion, filament winding, resin transfer molding, and compression molding and are available in liquid form and solid or powder form. They undergo curing mechanisms including room temperature curing, heat curing, and ultraviolet or radiation curing and are utilized by end use industry types including building and construction, pipes and tanks, transportation and automotive, marine, wind energy, and electrical and electronics.

What Is The Unsaturated Synthetic Polyester Resins Market Growth Forecast?

The unsaturated synthetic polyester resins market size is expected to see strong growth in the next few years. It will grow to $14.74 billion in 2030 at a compound annual growth rate (CAGR) of 5.8%.The growth in the forecast period can be attributed to increasing demand for lightweight automotive components, growing adoption of sustainable resin alternatives, rising expansion of renewable energy infrastructure, increasing use of advanced composite materials in aerospace applications, growing demand for high strength molded products. Major trends in the forecast period include increasing adoption of bio based unsaturated polyester resin formulations, growing development of low styrene emission polyester resin solutions, rising demand for high performance composite resin materials, increasing utilization of lightweight thermosetting resin systems, growing focus on corrosion resistant polyester resin applications.

What Is The Driver Of The Unsaturated Synthetic Polyester Resins Market?

The increasing demand from the construction industry is expected to propel the growth of the unsaturated synthetic polyester resins market going forward. The construction industry refers to the sector involved in the planning, design, development, building, and maintenance of infrastructure, residential, commercial, and industrial structures. The increasing demand from the construction industry is driven by rapid urbanization, as growing population centers require expanded residential, commercial, and infrastructure development. Unsaturated synthetic polyester resins help the construction industry by providing durable, corrosion-resistant, and lightweight materials that are widely used in applications such as reinforced plastics, panels, pipes, and coatings, improving structural performance and longevity. For instance, in June 2025, according to Eurostat, a Luxembourg-based statistical office of the European Union, in April 2025, construction production rose by 3.0% in the euro area and by 2.5% in the EU compared with April 2024. Therefore, the increasing demand from the construction industry is driving the growth of the unsaturated synthetic polyester resins industry.

Global Unsaturated Synthetic Polyester Resins Market Trends and Insights

Major companies operating in the unsaturated synthetic polyester resins market are focusing on developing advanced bio-based unsaturated polyester resins to reduce carbon emissions, decrease dependence on fossil-based raw materials, and support sustainable manufacturing practices. Bio-based unsaturated polyester resins are renewable-content thermosetting resins designed to deliver the mechanical and thermal performance of conventional petroleum-based resins while minimizing environmental impact. For instance, in May 2025, Bowden Chemicals, a UK-based supplier of raw materials for the polyester resin industry, secured an Innovate UK Smart Grant to develop an innovative bio-based unsaturated polyester resin (UPR). The 18-month project aims to create a resin containing more than 50% renewable content while maintaining the durability and performance of traditional UPRs. The new resin is intended to lower carbon footprint, reduce reliance on fossil fuels, and promote a more circular and sustainable production model for composite materials.
