ROHACELL® S
ROHACELL® S is a closed-cell rigid foam created using polymethacrylimide (PMI) chemistry, and it is entirely free of CFCs. This foam is self-extinguishing, meaning it has fire-resistant properties. It is well-suited for various applications, including use in rail vehicles, watercraft, and the aerospace industry, where fire safety is a critical consideration.

- 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.

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.
- Specification Compliance
ROHACELL® S can be supplied with test certificates confirming compliance with multiple specifications, including:; FAR 25.853 (a)(1)(i) AITM 2.0002 Small Burner Test vertical (60s); FAR 25.853 (a)(1)(ii) AITM 2.0002 Small Burner Test vertical (12s); FAR 25.853 (a)(1)(iv) AITM 2.0003 Small Burner Test horizontal (15s); FAR 25.853 (a)(1)(v) AITM 2.0003 Small Burner Test horizontal (15s); FAR 25.853 (d) AITM 2.0007 Determination of the specific optical smoke density of aircraft materials
- 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.
