About Unsaturated Polyester Resin Production Line

What is unsaturated polyester resin?

Unsaturated polyester resin (UPR) is a synthetic resin made through the polycondensation reaction of a dibasic acid (or anhydride) and a diol, followed by dilution with an unsaturated monomer (sych as styrene). It boasts mature processing, low cost and stable performance, making it one of the most widely used thermosetting resins worldwide.

Applications of Unsaturated Polyester Resin

• Fiberglass reinforced plastics: Ships, automotive parts, storage tanks, pipelines.
• Building materials: Artificial marble, decorative panels.
• Electrical industry: Insulation materials.
• Corrosion-resistant equipment: Chemical storage tanks, pipelines, fans.

Unsaturated Polyester Resin Production Process

Raw material preparation → Esterification reaction → Acid value testing → Cooling and dilution → Filtration and packaging
