The global unsaturated polyester resin market size was estimated at USD 14.75 billion in 2025 and is projected to reach USD 27.51 billion by 2033, growing at a CAGR of 8.3% from 2026 to 2033. Increasing use of fiber-reinforced plastics in water tanks, pipes, and storage vessels is consistently boosting demand for unsaturated polyester resins.
These applications prefer unsaturated polyester resin because of its low cost, good chemical resistance, and ease of processing on a large scale. Unsaturated polyester resins are mainly used in glass fiber-reinforced plastics (FRP). In addition, due to their various physical and chemical properties such as excellent tensile strength, impact resistance, bonding strength, and corrosion and heat resistance, these resins are extensively used in construction materials, housing equipment, and transportation equipment.
Global demand for unsaturated polyester resins is shifting from basic formulations to higher-performance, low-emission grades. Growth remains steady, driven by construction, marine, and transportation applications that require lightweight, corrosion-resistant composites. Manufacturers are investing in formulation innovation to improve toughness and cure speed while reducing volatile components. Simultaneously, the growing prominence of bio-based thermoplastics influences customer sourcing strategies, creating both competitive and complementary dynamics with thermoplastic solutions.
