ROHACELL is a polymethacrylimide (PMI) rigid closed cell foam used for lightweight sandwich construction. The natural color of ROHACELL is white. It has excellent mechanical properties, high dimensional stability under heat, good solvent resistance and outstanding creep compression resistance. The mechanical properties are presently not exceeded by any foam product having comparable density. ROHACELL, which is thermo formable, is furnished only in sheet form.
