Description: ROHACELL® is produced by thermal expansion of a co-polymer sheet of methacrylic acid and methacrylonitrile. During the foaming process the copolymer sheet is converted to PMI - PolyMethacrylImide. Alcohol is used as a blowing agent, thus ROHACELL® contains no fluorinated carbon hydrates and is halogen free. It has a very homogeneous cell structure and isotropic properties. Specific Notes for this Material: ROHACELL® IG (=Industrial Grade) is a closed-cell rigid foam plastic based on PMI (polymethacrylimide) which does not contain any CFCs. The fields of application for ROHACELL® IG are model building, vehicle construction and shipbuilding, as well as the manufacture of sports articles and X-ray tables. Information provided by degussa.
