the champion’s choice for TOP PERFORMING FOAM cores


Super lightweight ROHACELL® SL is a winning choice when it comes to structural core material for today’s demanding and high performing applications. A fiber-reinforced plastic (FRP) sandwich construction with ROHACELL® SL at the core can deliver an ideal solution. It provides excellent strength, plus bending stiffness when needed, as well as superior stabilization of thin FRP sheets that face extreme external forces.

ROHACELL® SL boasts outstanding mechanical strength, especially under tensile load, and a high tenacity. These attributes make it the perfect choice for applications with substantial dynamic mechanical loads.

Processing efficiency and versatility get high marks, too. ROHACELL®’s temperature stability facilitates processing at up to 180°C/356°F with all common processes, including vacuum infusion and resin transfer molding, pre-preg autoclaving, and hand lay-up. The high curing temperatures allow for reduced cycle times and excellent laminate properties. Its fine cell size minimizes surface resin absorption while maintaining a strong connection to the face sheet. At the same time, the closed-cell structure keeps the resin where you want it – in the interface.

Whether your design requires a simple shape or a complex 3-dimensional one, you'll find ROHACELL® SL sheets quick and easy to shape when routing, thermoforming or thermoshaping. Or let our Shapes Department do all the work and receive ready-to-use shapes that are ready for immediate processing.
