Description
ROHACELL® S is closed-cell rigid foam based on polymethacrylimide (PMI) chemistry that is completely free of CFC’s. This rigid foam is self-extinguishing and particularly suitable for applications in rail vehicles and watercraft, as well as use in the aerospace industry.
WEIGHT SAVINGS
When building composite sandwich components, lightweight ROHACELL® S has a closed cell structure that ensures the resin stays exactly where you want it – in the interface. This eliminates excess and unnecessary resin that adds undesirable weight to the finished part.
PROCESSING AND PRODUCTION
ROHACELL® S foam is suitable for both prepreg processing and vacuum infusion at temperatures up to 130 °C (266 °F) and pressures up to 0.35 MPa (50 psi). Curing method options include autoclave, RTM, VARTM and press.
Using a ROHACELL® core makes it possible to produce sandwich components in a single step (co-curing), resulting in reduced overall production time.
THERMOFORMING AND SHAPING
ROHACELL® S can be easily thermoformed or CNC machined to meet customer requirements. High precision, pre-shaped and ready-to-use foam cores in complex or simple geometries can also be supplied by the ROHACELL® Shapes Department.
