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® EC (= Electrically Conductive) is a closed-cell rigid foam plastic based on PMI (polymethacrylimide) which does not contain any CFCs. ROHACELL® EC is a specially developed material for applications were electro conductivity is desirable. Any commonly used manufacturing technique, such as autoclave, press molding and resin infusionb can be applied. Thermoformability is another advantage of ROHACELL® EC.
