★ Advantage of polycarbonate sheet
1Light weight : it is 1/2 weight of glass.
2Anti-uv: compared with glass, the uv coating pc sheet will not turn yellow /hazy/degrade under the sun exposure.
3High Light Transmission: up to 92%. The transmission loss is merely 6% in ten years, the transmission loss of PVC is 15% to 20% ,and 12% to20% of glass fiber
4Impact Resistance: 30times of acrylic and 250-300times of glass in the same thicknessNo crack appears after 3kg hammer falls down the sheet within 2m height.Therefore , it is called “infrangible glass” and “sound steel”.
5Bendability :It can be cold bending .The min bending radius is 175 times of thickness. It can be formed into arch and semicircular etc.
6Sound insulation: it is 3-4Db higher than glass at the same thickness . It is the international preferred noise barrier material on highway.
7Nonflammability: The nonflammability rate is rate B1, and ignition 580℃. It extinguishes automatically after leaving flame ,and doesnt produce toxic gas

Energy saving: The heat transfer coefficient is lower than glass and

other plastic ,the heat insulation is 7% to 25% above the glass in the same thickness and can reach up to 49%.

9Weatherability: it is good performance between -40℃ to 120℃. The yellow degree is 2 and light transmittance loss is just 6% after 4000hours accelarated aging test
10Temperature endurance:it doesn’t turn brittle at -100℃ and doesn’t turn soft at 135℃.
