How is downstream demand shaping the unsaturated polyester resin market outlook?
UPR demand splits into fiber-reinforced plastics (FRP) and non-FRP applications. FRP, combining UPR with glass fiber, is the largest and fastest-growing segment, feeding wind energy, rail transit, automotive, and construction. Non-FRP uses include artificial stone (quartz surfaces, marble), craft castings, gel coats, and coatings. Domestic production grew from 1.45 million tons in 2008 to 3.21 million tons in 2020, a 6.8% CAGR. Artificial stone, especially resin-based quartz for kitchen countertops, is a key value driver, demanding high-quality resin with low residual styrene to meet EU/US safety standards. The shift toward high-performance grades, such as corrosion-resistant and flame-retardant types, reflects stricter building codes and industrial upgrading.
