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.
