According to a research report published by Spherical Insights, the global Unsaturated Polyester Resin market size was worth around USD 13.58 billion in 2024 and is predicted to grow to around USD 32.59 billion by 2035 with a compound annual growth rate (CAGR) of 8.28% from 2025 to 2035.
the global Unsaturated Polyester Resin market size was worth around USD 13.58 billion in 2024 and is predicted to grow to around USD 32.59 billion by 2035 with a compound annual growth rate (CAGR) of 8.28% from 2025 to 2035. The global unsaturated polyester resin market is driven by increasing use in fiber-reinforced plastics, growing infrastructure and industrial projects, rising renewable energy applications, and the demand for corrosion-resistant, high-performance materials.
The global unsaturated polyester resin (UPR) market refers to the production and application of thermosetting resins made from unsaturated acids and glycols, which industries use to create fiber-reinforced plastics, coatings, and construction materials because these materials provide superior strength and resistance to corrosion and cost efficiency. The market expansion occurs because construction, automotive, marine, and wind energy industries require materials that combine lightweight characteristics with superior durability, while infrastructure projects continue to grow. In September 2024, Exel Composites entered into a purchasing agreement with INEOS to procure over 100 metric tons of its Envirez bio-based unsaturated polyester resin, marking commercial-scale adoption of low-carbon UPR in pultrusion and composite applications, supporting the industry’s shift toward sustainable materials
