Polycarbonate is a thermoplastic that comes in a transparent sheet. It is incredibly tough and absorbs minimal moisture, making it resistant to impact damage as well as water damage. It’s also flame-retardant and chemical resistant. Polycarbonate is durable, transparent and sanitary. This makes it effective in many different applications, including: Skylight, wall glazing, sign faces etc.
FRP sheets
Fiber-reinforced plastic (FRP) (also called fiber-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass (in fiberglass), carbon (in carbon fiber reinforced polymer), aramid, or basalt. Rarely, other fibers such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use .FRPs are commonly used in the aerospace, automotive, marine, and construction industries
