Unsaturated Polyester Resins Market Report 2026

The unsaturated polyester resins market size has grown strongly in recent years. It will grow from $11.82 billion in 2025 to $12.74 billion in 2026 at a compound annual growth rate (CAGR) of 7.8%. The growth in the historic period can be attributed to growth of construction industry, expansion of marine manufacturing, rising use of composites, availability of cost effective resins, increasing infrastructure projects.

The unsaturated polyester resins market size is expected to see strong growth in the next few years. It will grow to $16.8 billion in 2030 at a compound annual growth rate (CAGR) of 7.2%. The growth in the forecast period can be attributed to growth in renewable energy installations, increasing electric vehicle production, rising demand for corrosion resistant materials, advancements in composite processing, expansion of transportation manufacturing. Major trends in the forecast period include rising use in fiber reinforced plastics, growing demand from marine applications, increasing adoption in automotive components, expansion of resin use in wind energy, rising focus on lightweight composite materials.

Growth in the construction industry is significantly contributing to the expansion of the unsaturated polyester resins market. The construction industry involves maintaining, repairing, and building new structures. The increasing activity in building and infrastructure development supports demand for unsaturated polyester resins due to their properties such as rapid strength gain, chemical and corrosion resistance, high impact strength, and strong compressive performance - all of which are beneficial in various construction applications. For example, in July 2023, the Australian Bureau of Statistics, an Australian government agency, reported that the number of dwellings under construction increased to 240,813 in the March quarter of 2023, up from 240,065 in 2022. Among these, new houses totaled 103,778 in 2023, compared to 101,240 the previous year. Therefore, the growth of the construction industry is driving the demand for unsaturated polyester resins.

Major companies in the unsaturated polyester resins market are focusing on developing innovative bio-based resins to reduce environmental impact, improve sustainability in production, comply with stricter regulations, and meet rising consumer demand for eco-friendly materials. Bio-based unsaturated polyester resin is a synthetic polymer derived mainly from renewable sources such as natural oils, starches, or other plant-based feedstocks, rather than traditional petroleum-based materials. For example, in October 2024, Exel Composites, a Finland-based manufacturer of pultruded and pull-wound composite solutions, launched a new bio-based unsaturated polyester resin designed to advance sustainability in composite manufacturing. Derived from renewable resources, this resin offers an environmentally friendly alternative to conventional petroleum-based resins and is especially suitable for automotive and transportation applications focused on reducing carbon footprints. The resin maintains high durability and performance levels, making it an appealing choice for manufacturers seeking greener materials without compromising quality or efficiency.

In March 2025, KPS Capital Partners, a U.S.-based private equity firm, acquired the global composites business of INEOS Enterprises for an undisclosed amount. Following the acquisition, the business was rebranded as Alta Performance Materials. This transition enables the newly formed entity to expand its global footprint in unsaturated polyester resins (UPR), strengthen its manufacturing capabilities, and enhance its product offerings across sectors such as construction, marine, automotive, and industrial applications. INEOS Enterprises Holdings Limited is a UK-based provider of unsaturated polyester resins.
