FEATURECharacteristics of PC twin-wall sheet:1, light transmittance: the light transmittance of the PC sheet is up to 89%, compare favorably with the glass. Sheet with UV coating does not turn yellowing, atomization, poor light transmission in the exposure sunlight, the loss of transmittance is only 6% after 10 years, but the PVC wastage rate is as high as 15% to 20%, and the glass fiber is 12 % -20%.2.anti-impact: PC sheet is the best impact resistance of thermoplastics, the impact resistance of polycarbonate is 10-27 times than glass and plexiglass 3.UV protection: It is coated with anti-ultraviolet (UV) coating on one side and with anti-condensation processing on the other side, with the function of anti-UV, heat insulation and anti drop. It can prevent the ultraviolet rays pass through, and suitable to protect the precious works of art and exhibits from UV damage.4.Light weight: the proportion is only 1/12 of the ordinary glass, and not easily crushed, save transport, unloading, installation, and the cost of the support frame.5.The flame: the national standard GB50222-95 confirmed the PC board is the number one level of fire-resistance, ie B1 level. The ignition point of PC sheet is 580 degrees Celsius, the combustion does not produce toxic gases from the fire self-extinguishing, will not contribute to the spread of fire.6.Bendable: It can use cold-formed way at the site according to design, install into arched, semi-circular roof and windows. Minimum bend radius is 175 times the plate thickness, It also can be hot bended.7. Sound insulation: The noise effects of the sun panels is significantly, which has the better sound insulation than the same thickness of glass and acrylic plate. Under the same conditions, the PC sheet of sound insulation can improve 3-4DB than glass. it is the material of choice for highway noise barriers in the international arena8.Energy-saving: It keep cool in summer, and keep warm in winter, The thermal conductivity (K value) of PC sheet is more lower than ordinary glass and other plastic, the insulation effect of PC sheet is 7% -25% higher than the same glass, the hest insulation is up to 49%. So that heat loss is greatly reduced, it is used to warm the equipment building, an environmentally friendly material.9.Temperature adaptability: sun panels will not crisp at the temperature of -100 ℃, and won’t softening at 135 ℃ , mechanical performance was no significant change in the harsh environment.10.weather resistance: The sun panel can maintain the physical stability of the indicators in the range of -40 ℃ to 120 ℃. Artificial weathering test of 4000 hours, yellowing is 2, light transmittance value is only 0.6% lower11.Anti-condensation: outdoor temperature is 0 ° C , indoor temperature of 23 ° C, indoor relative humidity less than 80% of the inner surface of the material, non-condensing
