PMMA – Polymethyl methacrylate
PMMA SUPER
PMMA SUPER is an amorphous thermoplastic PMMA with an impact strength much greater than that of standard PMMA. The material is available in a wide range of impact strength grades, with the strongest approaching polycarbonate in its impact resistance. We deliver PMMA Super as sheets.
