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, a reactive diluent, 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.
Composites built of UP/VE resins, glass fibers and/or other reinforcements are used in market sectors like:
Safe Handling Guides
The UP Resin Safe Handling Guides address the key health, safety and environmental issues associated with the storage and processing of raw materials in the UP/VE resin industry. This includes advice and guidance to ensure good housekeeping when using UP resins, as well as specific recommendations on styrene exposure and abatement, Personal Protective equipment (PPE), and legislation governing UP resins in the EU.
