Chemical Composition

ROHACELL is manufactured by hot forming of methacrylic acid/methacrylonitrile copolymer sheets. During foaming this copolymer is converted to polymethacrylimide.Information supplied by Emkay Plastics, Ltd

Advantages
  • low density grade
  • very high strength
  • closed-cell rigid expanded plastic material for light weight sandwich construction
  • excellent mechanical properties
  • high dimensional stability under heat
  • solvent resistance
  • particularly at low temperature, a low thermal conductivity
  • highest strength and moduli values
  • highest for any foamed plastic in its density range
