Unsaturated Synthetic Polyester Resins Market Forecast: Value Set To Climb From $11.79 Billion To $14.74 Billion
The unsaturated synthetic polyester resins market has seen robust growth over recent years. It is projected to expand from $11.1 billion in 2025 to $11.79 billion in 2026, achieving a compound annual growth rate (CAGR) of 6.2%. Historically, this growth has been driven by several factors, including the escalating demand for composite materials in construction, the rising use of fiberglass reinforced plastics in industrial equipment, the increasing application of polyester resins in marine and transportation sectors, the expanding manufacture of wind energy components utilizing composite materials, and a heightened need for durable and corrosion-resistant materials.
The unsaturated synthetic polyester resins market size is set to experience robust expansion over the next few years, with projections indicating it will reach $14.74 billion by 2030, advancing at a compound annual growth rate (CAGR) of 5.8%. This anticipated growth is primarily fueled by the escalating demand for lightweight automotive components, the increasing embrace of sustainable resin alternatives, the continuous expansion of renewable energy infrastructure, the wider application of advanced composite materials in aerospace, and the growing need for high-strength molded products. Furthermore, significant trends expected within this period include the rising adoption of bio-based unsaturated polyester resin formulations, the continued development of low styrene emission polyester resin solutions, an increasing requirement for high-performance composite resin materials, enhanced utilization of lightweight thermosetting resin systems, and a heightened focus on corrosion-resistant polyester resin applications.

Unsaturated Synthetic Polyester Resins Market Trends Redefining Industry Growth
Major companies operating in the unsaturated synthetic polyester resins market are concentrating on developing advanced bio-based unsaturated polyester resins. This focus is aimed at reducing carbon emissions, decreasing dependence on fossil-based raw materials, and supporting sustainable manufacturing practices. Bio-based unsaturated polyester resins are thermosetting resins containing renewable content, specifically designed to provide the mechanical and thermal performance of conventional petroleum-based resins while minimizing environmental impact. As an illustration, in May 2025, Bowden Chemicals, a UK-based supplier of raw materials for the polyester resin industry, was awarded an Innovate UK Smart Grant to develop an innovative bio-based unsaturated polyester resin (UPR). The 18-month project’s goal is to create a resin containing more than 50% renewable content, ensuring it maintains the durability and performance of traditional UPRs. This new resin is intended to lower the carbon footprint, reduce reliance on fossil fuels, and promote a more circular and sustainable production model for composite materials.
