What Is Unsaturated Polyester Resin?
Unsaturated polyester resin (UPR) is a thermosetting liquid polymer that hardens when combined with a catalyst and accelerator.
It is the primary matrix material used in Fiber Reinforced Plastic (FRP) manufacturing, forming strong, lightweight and corrosion-resistant composite structures when combined with glass fibre reinforcements.
Benefits of Unsaturated Polyester Resin
- Excellent mechanical strength and rigidity
- Good chemical and corrosion resistance
- Versatility across multiple manufacturing processes
- Cost-effective compared to other thermoset resins
- Easy processing in open and closed mould systems
