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. |
