ROHACELL® IG-F Polymethacrylimide Foam

Subcategory: Composite Core Material; Polymer; Polymethacrylimide; Thermoset

Material Notes:
ROHACELL 110 is a specialty grade which closes the gap between lower-density grades (31, 51, and 71) and the compacted, higher-density grades (P 170 and P 190).

General ROHACELL Information: ROHACELL is a closed-cell rigid expanded plastic material for lightweight sandwich construction. It has excellent mechanical properties, high dimensional stability under heat, solvent resistance and, particularly at low temperature, a low thermal conductivity. The strength and moduli values are the highest for any foamed plastic in its density range. ROHACELL is manufactured by hot forming of methacrylic acid/methacrylonitrile copolymer sheets. During foaming this copolymer is converted to polymethacrylimide.
