About Polycarbonate

Properties of Polycarbonate

1. Property of Heat:
  • Temperature of Heat deformation: The temperature that causes Polycarbonate panels to deform is 130°C, and the highest temperature for continuous using is about 120°C.
  • Coefficient of Linear Expansion: Polycarbonate is one of resin which has smaller coefficient of liner expansion.
  • Conductivity of Heat: There is no big difference between heat conductivity of Polycarbonate and other resin. It’s about 1/4 of Glass, 1/300 of Iron, 1/1000 of Aluminum, 1/12000 of Steel. Polycarbonate is a better material to keep warmth.
  • Temperature of Embrittlement: For embrittlement, Polycarbonate is lower than normal resin. It’s about -135°C, and the lowest temperature for continuous using is about -30°C.
  • Combustion: Polycarbonate is one of resin which gets burn not easily. During the process of heating up Polycarbonate, Polycarbonate would not produce toxic gas.
2. Property of Optics:
  • Weather Ability: When normal Polycarbonate panels are exposed outdoor for a long time, normal Polycarbonate panel become yellowish and crack on the surface. The surface of Polycarbonate panel, made by SUN ASIA, is all coating with Anti-UV material. As the results, the optic property and mechanical property would not have significant changes even under the exposure for a long time.
  • Diaphaneity: The diaphaneity of 1mm thickness clear Polycarbonate panel is above 85%, and the diaphaneity of 5mm thickness clear Polycarbonate panel is above 80%, similar with glass.
3. Mechanical Property:
  • Pull Resistance: Polycarbonate panel have better heat resistance. Even under 120°C, the pull resistance is still 350kgf/cm2.
  • Modulus of Bending Resistance: Polycarbonate panel have better bending resistance. Polycarbonate panel would not break, even if the angle is 80° ~ 90°.
4. Sound Insulation Property:
  • As the thickness is the same, the sound insulation property of Polycarbonate panels is better than glass under the high frequency.
5. Property of Weight:
  • At the same dimension, the weight of Polycarbonate board is half of glass. This can help us to save the cost of delivery and haul or construct more easily.
