Evonik Rohacell® 110 A Aircraft Grade Polymethacrylimide (PMI) Foam (discontinued **)
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoset; Polymethacrylimide
Material Notes:	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® A (Aircraft grade) is a closed-cell rigid foam plastic based on PMI (polymethacrylimide) which does not contain any CFCs. The field of application for ROHACELL® A is aircraft construction. Curing temperature up to 130C (266F). Curing pressure up to 0.35 MPa (50 psi). Sandwich components using ROHACELL® A as 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. ROHACELL® A is easy to shape. Thermoformability is another advantage of the core material. Information provided by degussa. Evonik Industries is the successor company to Degussa.
