Features:
1) Impact strength: The impact strength of solid PC sheets is 250 times that of glass, and the impact strength of hollow PC sheets is 80 times that of glass
2) Light weight: The weight of a solid PC sheet is only about half of glass, and the weight of a hollow PC sheet is only about one twelfth at the same thickness
3) Transparency: The light transmission of a 3mm solid PC sheet is 88%, and the light transmission of a6mm hollow PC sheet is 80%
4) UV-protection: A PC sheet is co-extruded with a high-density ultra violet ray that also keeps the PC sheet from discoloring
5) Resistance to weather: A PC sheet has resistance to bad weather and maintains excellent properties in a wide temperature range from -40 to 120oC
6) Inhibiting condensation: When the outdoor temperature is 0oC and the indoor temperature is 23oC, the PC sheet will be condensation up to 80% humidity
7) Thermal insulation: The K-value of glass is 1.2 times that of solid a PC sheet and is 1.7 times that of a hollow PC sheet. PC sheets saves energy while preventing heat loss
8) Sound insulation: The hollow form and polycarbonate resin offers significant advantage to that of glass
9) Flame Resistance: Through testing by the National Center for Quality Supervision & Testing of Fire Building Materials, the material is rated as Class B1 according to QB8624-1997 standards
10) Easy installation: A PC sheet can be bent while hot or cold and can be used on curved roves and windows. The minimum radius of curvature of a PC sheet is 175 times of its thickness.

2) Maximum width: 2, 100mm
3) Length: Any dimension
4) Specific gravity: 1.2
5) Color: Clear, blue, green, opal, brown, blue green etc.
