Polyester resin for pultrusion
2016-11-28

UPR (Unsaturated polyester resin) is the most widely employed, simply beacuse they demonstrate a combination of properties that are not only well suited to the pultrusion process but, through chemical and additive alteration, permit ready and critical modification to answer specific process and finished profuct performance demands. Their low viscosity, for example, promotes quick and total reinforcement wet-out, and their high ploymerisation reacticity allows for a fast but totoally controllable cure within the pultrusion die. Of supreme imporatance, the UPR defines much of the commerical success of the process. 

      UPR offer high strength and resiliency, They can be specially formulated for a wide range of demanding physical and mechanical property applications, including good resistance both to the weather and a variety of chemical media.
