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.
