1, Impact resistance: impact polycarbonate panels can be up to 3kg/cm, the impact strength of PC sheet is 250-300 times that of ordinary glass, acrylic sheet is 20-30 times, the glass is two-fold, almost No risk of fracture. The following two meters with a 3kg hammer falling and no cracks, there is "no broken glass" and "ring of steel" reputation. 2, the light transmittance: excellent light transmittance of up to 75 ~ 90%, and its transparency comparable to glass. In the sunlight will not produce yellowing, fogging, light is poor. UV coated plate in the sunlight prolonged sun exposure does not produce yellowing, atomization, poor light, only ten years after the loss of light transmission 6%, PVC turnover rate is as high as 15% -20%, the glass fiber is 12 % -20%. 3, weathering resistance: The surface layer co-extruded UV resin fatigue prevents UV-induced yellowing sunlight. Surface layer co-extruded with a chemically absorb UV and converted into visible light, photosynthesis of plants have a good stabilizing effect. Outdoor guaranteed years without fading. In the range of -40 ℃ to 120 ℃ to maintain the stability of the physical indicators. Artificial weathering test 4000 hours, yellowing of 2, to reduce the transmittance value is only 0.6%. 4, flame resistance: solid sheet itself is not spontaneous combustion and has a self-extinguishing. EU ROHS Directive and the stringent UL safety regulations, UL94 V0 class fire rating, V2 level, HB level. PC board itself ignition is 580 degrees Celsius, away from the fire self-extinguishing, does not produce toxic gases when burned, will not contribute to the spread of fire. 5, heat resistance, cold resistance: In the Celsius temperature -40 ℃ to +120 ℃ range without causing deformation of quality deterioration. PC board at -100 ℃ cold brittle when not happen when not soften at 135 ℃, in the harsh environment there was no significant change in his mechanics, mechanical properties. 6, hard light: light weight, only half of the glass, acrylic plate 1/3, good adaptability and security, ease of handling, drilling, when truncated to install, easy to break, easy construction process. 7, bendable: according to the design using cold-formed at the site, the installation arched, semi-circular roof and windows. The minimum bend radius is 175 times the thickness of the use, but also bending. 8, noise: PC board insulation effect is obvious, there is a better sound insulation than the same thickness of glass and acrylic plate, under the same conditions thickness, PC board insulation than glass improved 3-4DB. Is the preferred material for highway noise barriers in the international arena. 9, energy efficiency: 夏天保 cold, winter insulation, PC board even less than ordinary glass and other plastic thermal conductivity (K value), thermal insulation effect of 7% -25% higher than the same glass, PC board insulation maximum 49%. So that heat loss is greatly reduced, the equipment used to warm the building, an environmentally friendly material. 10, anti-condensation: outdoor temperature is 0 ℃, the indoor temperature is 23 ℃, indoor relative humidity below 80%, non-condensing inside surface of the material.
