Rohacell® 71 IG Industrial Grade Polymethacrylimide (PMI) Foam

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.
