Lexan (LEXAN) is a registered trademark for SABIC Innovative Plastics' (formerly General Electric Plastics) brand of highly durable polycarbonateresinthermoplastic intended to replace traditional glass and Plexiglas where the need for strength and impact resistance justifies its higher cost. It is a polycarbonate polymer produced by reacting Bisphenol A with carbonyl chloride, also known as phosgene. Lexan is the brand name for polycarbonate sheet in thicknesses from 0.75 mm (0.03 in) to 12 mm (0.48 in) and resin in a wide range of grades. Applications are mainly in three domains — building (glazing and domes), industry (machine protection and fabricated parts) and communication and signage.
