CHE SIGNIFICA PERSPEX IN INGLESE
Polimetilmetacrilato)
Poly è un termoplastico trasparente spesso utilizzato come un'alternativa leggerissima o anti-batteria al vetro. Anche se non è tecnicamente un tipo di vetro, la sostanza a volte è stata chiamata storicamente vetro acrilico. Chimicamente, è il polimero sintetico di metil metacrilato. Il materiale è stato sviluppato nel 1928 in diversi laboratori di molti chimici come William Chalmers, Otto Röhm e Walter Bauer e fu commercializzato per la prima volta nel 1933 dalla Rohm and Haas Company, con il marchio Plexiglas. Da allora è stato venduto sotto molti nomi diversi, tra cui Acrylite, Lucite e Perspex. PMMA è un'alternativa economica al policarbonato quando non è necessaria una forza estrema. Inoltre, PMMA non contiene le potenzialmente dannose subunità di bisfenolo A trovate in policarbonato. È spesso preferito a causa delle sue proprietà moderate, di facile manipolazione e di lavorazione e di basso costo. Il PMMA non modificato si comporta in modo fragile quando viene caricato, soprattutto sotto una forza di impatto, ed è più soggetto a graffiare rispetto al vetro convenzionale inorganico, ma la PMMA modificata può ottenere una resistenza ad elevata resistenza agli urti e agli urti.
