Much is reported, and in fact now being seen universally, about “Infection Protection” barriers and dividers made from “Plexiglass” as this pseudo mark is referred to.
Some background: Originally trademarked Plexiglas® in 1933 by Rohm und Haas in Germany, now owned by Arkema France.
First used as a glass substitute; one of the first applications was airplane windows.
Other trademarks for acrylic sheet are Acrylite®, Lucite®, Perspex® and Altuglas®
