Evonik (ROHACELL) Reported
ROHACELL polymethacrylimide rigid closed-cell foam core for glass fibre sandwich structures. PMI survives autoclave cure without crushing and can be machined and thermoformed to shape, which is why it appears in radomes and control surfaces. US production at Mobile, Alabama. Grade list, density range and temperature capability were not captured, and WHICH grades are made at Mobile, Alabama rather than Darmstadt is not established. Confirm the producing plant for your grade if domestic content matters.
