What is Lexan?
Lexan is a brand of polycarbonate which, inter alia, can be used in the production of chair mats.
It is registered for SABIC Innovative Plastics (formerly General Electric, GE Plastics).
Dr. Hermann Schnell of Bayer in Germany invented the polycarbonate in 1953, just one week before chemist Dr. Daniel Fox of GE independently made the same discovery. They had created a gooey substance that once hardened, could not be broken or destroyed. Both teams were impressed by the remarkable toughness of polycarbonate.
