About UP/VE resins

Unsaturated polyester (UP) resins and epoxy vinyl ester (VE) resins are liquid products containing linear unsaturated polyester polymers respectively epoxy vinyl ester polymers (50-70%) and mainly styrene (30-50%). The role of styrene is first to dissolve the polymers for good application properties when adding the reinforcement and secondly to take part in the curing process by cross linking the linear polymers and creating the final reinforced structure or composite.

By choosing different raw materials in building the linear UP/VE polymer, different final properties of the composites can be achieved like; high mechanical strength compared to weight, excellent corrosion resistance, electrical properties (isolating), good thermal properties and flame retardant properties, etc.
