Classic Case Study – EXTREN 625

FRP (fiberglass reinforced plastic) products may seem like a new product – but they’re not. In fact, Redco FRP’s manufacturer, Strongwell, has been in business since the 1950’s! For many decades now FRP has shown its versatility, strength and longevity in countless applications. Recently Strongwell’s Marketing Department posted a case study from 1993 in which EXTREN series 625 (polyester resin, fire-retardant) grade FRP was used in the chlorine manufacturing division between the cells. However, FRP with the more corrosion resistant vinyl-ester resin was selected for the chlorine manufacturing area itself. In addition to the corrosion-resistance, there was a potential electrical hazard meaning the use of conductive materials had to be minimized. FRP is non-conductive and this provided an added safety benefit in the application.
