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.

Дреимущества
- very homogeneous cell structure
- isotropic properties
- Extended Temperature
- closed-cell rigid foam plastic based on PMI (polymethacrylimide)
- does not contain any CFCs
- serves as a core material in advanced BMI-sandwich parts
- easy to shape
- Thermoformability
- Curing temperature up to 190C (374F)
- Curing pressure up to 0.7 Mpa (100 psi)
- post-curing temperature (free-standing) up to 230C (446 F)
- Sandwich components using ROHACELL® XT as a core material can be realized in a single work step (=cocuring). The structural components can be manufactured in an autoclave and by means of RTM.
