Unsaturated polyester resins are thermosetting polymers formed by the reaction of unsaturated acids and glycols. They are widely used in reinforced plastics and non-reinforced applications due to their versatility, durability, and cost-effectiveness. These resins play a pivotal role in producing fiberglass-reinforced plastics (FRP), which are extensively used in construction, marine, automotive, and electrical industries.
With infrastructure projects booming worldwide and growing awareness about sustainable materials, manufacturers are increasingly developing bio-based and low-styrene UPR solutions to align with environmental regulations and end-user preferences.

Key Market Drivers

Booming Construction Sector

The construction industry remains the largest end-user of unsaturated polyester resins. Rising demand for roofing materials, wall panels, and bathroom fixtures, combined with urbanization in emerging economies, is creating strong growth opportunities.
