ROHACELLÆ 110 Polymethacrylimide (PMI) Rigid Foam Sheet

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 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.
