Antifragmentation plates of polymethylmethacrylate

摘要

Antinoise and antifragmentation plates based on acrylic polymers employing a polymeric continuous film placed inside the plate, wherein the film is characterized by an elastic modulus lower than the one of PMMA of at least 30%, and/or elongation at break higher than at least 40%, measured by the test according to ISO 527 standard for plates or for films.
