Rohacell SL

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 Chem-craft Shapes Department do all the work and receive ready-to-use shapes that are ready for immediate processing.

Description

The trend continues toward designing lightweight, better performing products. The manufacturing process to create innovative new products and their components must be cost efficient and reliable. In many cases, the demanding requirements call for fiber-reinforced plastic (FRP) sandwich construction to deliver the ideal solution. Whether the goal is excellent bending stiffness & strength, stabilization of very thin FRP sheets against external forces, or generating complex 3-D geometries with minimized effort – a ROHACELL® sandwich can be the answer.

STRENGTH AND DURABILITY

ROHACELL® SL foam cores boast outstanding mechanical strength, especially under tensile load, and a high tenacity. These attributes make it a great choice for applications with substantial dynamic mechanical loads.

ROHACELL® HELPS YOU SAVE WEIGHT

The 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.

FAST AND EFFICIENT PROCESSING Excellent temperature stability facilitates processing up to 180 °C (356 °F) for ROHACELL® SL 71 or ROHACELL® SL 110, and up to 170 °C (338 °F) for ROHACELL® SL 200, with all common processes like vacuum infusion and resin transfer molding, pre[1]preg autoclaving, hand lay-up, and compression molding. High curing temperatures allow for reduced cycle times and excellent laminate properties. ROHACELL® SL is easy to shape by routing or thermoforming.
