ROHACELL® SL
ROHACELL® SL foam cores exhibit exceptional mechanical strength, particularly under tensile loads, and high tenacity. These characteristics make it an excellent choice for applications subjected to significant dynamic mechanical loads. A ROHACELL® sandwich can provide the solution for achieving goals like excellent bending stiffness and strength, stabilizing thin FRP sheets against external forces, or creating complex 3-D geometries with minimal effort.

- Attributes
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, with all common processes like vacuum infusion and resin transfer molding, pre-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.
