Technical Documents
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.

Advantages
- very homogeneous cell structure
- isotropic properties
- closed-cell rigid foam plastic based on PMI (polymethacrylimide)
- does not contain any CFCs
- Curing temperature up to 130C (266F)
- Curing pressure up to 0.35 MPa (50 psi)
- easy to shape
- Thermoformability
- Sandwich components using ROHACELL® HF as core material can be realized in a single work step (= cocuring).
Other Applications
The fields of application for ROHACELL® HF are antennas,radomes and X-ray tables.
