Description
[GE Structured Products] A registered trademark for a thermoplastic Polycarbonate (PC) sheet that was first marketed in 1959. Lexan sheets are clear, strong, have good weather resistance and are often used for optical products, optical discs, sunlight panels, etc. They have a lower softening temperature than Plexiglas and do not fracture as easily. Most of the Lexan sheets are UV stabilized to provide a resistance to yellowing that is similar to acrylic sheets. Lexan can be used as windows and doors glass. PC laminates are widely used in banks, embassies, detention and public places for protective windows, aircraft hatch covers, lighting equipment, industrial safety panels and bulletproof glass.
The manufacturer lists the following cleaners as compatible with Lexan sheets: Freon, VM&P naphtha, Windex with Ammonia D [Dracket Products], Top Job [Proctor & Gamble], Joy [Proctor & Gamble], Palmolive Liquid [Colgate Palmolive] and Formula 409 [Clorox Co.],
Synonyms and Related Terms
polycarbonate sheet
