Huntsman is a leading global producer of maleic anhydride – a key ingredient required for manufacturing unsaturated polyester resins (UPR). Demand for UPR is growing rapidly to enable the production of lighter, stronger, fiberglass composites for boats, automotive, construction, bridges, wind turbine blades, pipes, decorative architectural features and a highly varied range of consumer products. Wherever they are used, these resins offer greater flexibility for innovative designs, improved performance and faster production speeds. They are also highly durable offering a lightweight, low-maintenance, practical alternative to conventional materials. As a versatile intermediate, Huntsman’s maleic anhydride can be used in UPR as a key component to make up the polymer matrix, combining mixes of petro- or plant-derived chemicals.
