   Due to the PC board having many kinds of characteristics of good impact resistance, high strength, break resistance, good weathability, light transmittance, high plasticity, light weight, heat insulation, non-flammability, anti-UV, long service life and so on,  the polycarbonate board is widely used in various industries.      Characteristics::   Processing properties: single PC board can be made into many kinds of modeling fittings by the methods of vacuum forming and pressure forming; Double PC board also can form cold bending in ordinary temperature. On site, it can be cold bended, install arched and hemicycle top or windows according to drawings. Minimal bending radius is 100 times as thickness as used board, also it can be hot bended.     Advantages of polycarbonate:    Light transmittance: The daylighting is admirable, and the light transmittance rate is up to 85%-91%, so its transparency can be comparable with glass. In sunlight it won’t produce the phenomenon of yellowing, fogging and less light transmittance. UV coated board in the sun does not produce the phenomenon of yellowing, fogging and less light transmittance. The rate of losing light of PC board is only 6%, but PVC is as high as 15%-20% and glass fiber is 12%-20% ten years later.   High plasticity: The PC board can be installed into the arched and semicircular ceiling according to the design drawing on the live site with cold formed way. The minimal bending radius is 100 times the thickness of the used board.   Energy saving: It keeps building cool in summer, and keeps them warm in winter. The thermal conductivity (Kvalue) of PC board is lower than common glass and other plastics. The effect of heat insulation is 7%-25% higher than glass with equal level. The highest rate of heat insulation is 49%. Thus it can reduce heat loss greatly, and suit for buildings with warm equipments, which belong to environmental protection material.   Preventing dewing: When the outdoor temperature is 0 centigrade, the indoor temperature is 23 centigrade and the relative humidity indoor is under 80%, so the inside surface will not dew.   Impact resistance: The impact resistance of PC board is up to 3kg/cm. The PC board is 250-300times the impact resistance of the general glass, is 20-30 times of the PMMA plate, and is 2 times of the toughened glass, which make it hard to break and don’t have the risk of fracture. It will not crack, when hit by less than 3kg of hammer which drops from two meters. So it enjoyed the reputation of being “unbreakable glass” and “ring of steel”.   Weatherability: The surface is covered with anti-ultraviolet co-extrude layer, which can prevent resin from aging and yellowing caused by the sun’s ultraviolet rays. The surface of co-extrude layer with chemical bond can absorb the ultraviolet radiation and translate it into visible light, which has a good stable effect to the plant photosynthesis. It makes sure that it will not fade outdoor in ten years. It can keep all the physical indexes stable within -40 centigrade to 130 centigrade. The yellowing degree is only 2, and the decreasing value of light transmittance is only 0.6 percent.     Resistance to flammability:   PC board itself can not be spontaneous combustion, and it can quench by itself. It is in accord with the instruction of European Union ROHS and the strict safety standard of UL, and UL 94 fire prevention grade is up to level V0, level V2, level HB. PC board’s flash point is 580 centigrade. It will quench when getting away from the fire and it will not produce toxic gases and not contribute to spreading the fire while burning.   Resistance to heat, resistance to cold : During the temperature from -40 centigrade to +130 centigrade, it will not cause deformation or degrading the quality. PC board will not be brittle in -100 centigrade, as well as be softened in 137.3 centigrade. Its mechanics and mechanical properties don’t have obvious changes in hostile environments.   Lightness & Rigidness:   It is light. It is only half weight of the glass, 1/3 the weight of acrylic board. Owing to good adaptability and safety, it is easy to handle, drill. When installed, it is not breakable, and construction is simple and safe.   Sound insulation:   The effect of sound insulation of PC board is obvious, it is more effective than glass board and acrylic board with the same thickness. In the same conditions of thickness, the quantity of PC board’s sound insulation is 3-4DB larger than glass. It is the first choice as material to be used in highway noise barriers in the word.
