Polymethacrylimide Foam

Polymethacrylimide Foam   Polymethacrylimide (PMI) foam is a cross-linked rigid structural foam material with a 100% closed-cell structure. Its uniform cross-linked cell wall structure gives it an outstanding and stable structure, and its mechanical properties are the strongest among existing foams of the same density.   Feature of Polymethacrylimide Foam Waterproof: 100% closed cell structure and isotropic.
