About polycarbonate

Polycarbonate is called a transparent metal, and it is a lightweight and tough transparent material which is easy to form and hard to break when compared to glass. Furthermore, it has better flame retardancy compared to acrylic, and has been widely recognized as a safe material. Like vinyl chloride, there is no concern regarding toxic gas at the time of incineration.


  • High shock resistance
    • About 200 times higher than glass of the same thickness, and about 30 times higher than acrylic
  • Lightweight
    • About half the weight of glass due to its specific gravity of 1.2
  • Flame retardancy
    • Flames naturally go out when moved away from a flame source, and there is less concern over toxic gas compared to plastics
  • Easy processing and forming
    • Cutting, drilling, and notching are easy, while cold forming which bends with heat forming and at normal temperatures is also possible.
  • Wide range of working temperature
    • From -40℃ to +125℃ (from 0℃ to 90℃ for acrylic)
