Product Name: Polycarbonate panels Material: Polycarbonate material: Bayer materials and imported materials Sabic (formerly the American GE material) Thickness: 1.5mm 2mm 3mm 4mm 5mm 6mm 8mm 10mm 12mm15mm 20mm (customized thickness range 0.125mm-20mm) Dimensions : roll 1.22m / 1.56m / 1.82m / 2.1m * 30m; sheet: 1.22m * 2.44m 1m * 2m; (the other can be customized: width 0-2.5m, length: optional) Color: Transparent sapphire cream Green Lake and other green brown (other colors can be customized) Polycarbonate panels feature: a, mechanical properties 1) impact strength: PC solid sheet with excellent impact resistance, it is 300 times higher than conventional glass, 30 times higher than the acrylic sheet. The impact strength of PC sheet is like saying "transparent plate," he said. 2) good tensile strength, PC solid sheet heat resistance, even at 120 ℃, its tensile strength is still up 350kgf / cm2. 3) bending strength: PC solid sheet bending is good, even if the bending angle of 90 °, still broken. b, thermal performance 1) Melting temperature shape: PC Solid sheet-shaped melting temperature of 135 ℃, their continuous use temperature of 120 ℃. 2) linear expansion coefficient: linear expansion coefficient of 7 × 10-5cm / cm / ℃ in plastic in the case of smaller. 3) Brittle temperature: PC solid sheet brittle transition temperature of -40 ℃, the minimum continuous use temperature of -30 ℃, is generally not comparable plastic. 4) Flammability: PC solid sheet is a flame retardant self-extinguishing plastic one, it does not produce toxic gases when heated to high temperatures. ULR-94 certification, flame retardant B1 level fire drops, no gas; 5) Thermal conductivity: PC solid sheet of thermal conductivity does not differ greatly and general plastic, glass 1/4 1/300 iron, aluminum 1/1000, 1/2000, is one of the excellent insulation properties of the material such as copper. c, the optical properties of 1) transmittance: PC solid sheet of light transmittance of 88% and a glass quite. 2) Weather resistance: general long-term exposure to outdoor PC endurance plate, by ultraviolet radiation can lead to yellowing and surface degradation. Czech anti-PC sheet surface with a layer of anti-UV layer, even if long-term exposure to outdoor, optical and mechanical properties did not change significantly. d, noise performance: Czech resistance to the effect of noise is higher than the PC sheet glass 3-4DB, is currently the preferred material for highway noise barriers. e, light weight: Under the same thickness and area, PC solid sheet is only half the weight of glass, so you can save a lot of handling and construction difficulty and shipping. Sunshine board features: translucent: PC board transmission rate of up to 89% glass phase deceased mother with the United States. UV coating plate in the sunlight prolonged sun exposure does not produce yellowing, fogging, poor light transmittance loss after ten years only 6%; anti-impact: the impact strength is 250-300 times that of ordinary glass; anti- UV: PC board side coated with anti-ultraviolet (UV) coating on one side with anti-condensation process, set UV, heat insulation anti Dettol functions in one. Light weight: save transportation, moving unloading, the cost of installing and supporting frame. Retardant: the national standard GB50222-95 confirmation, PC board for the flame level, namely B1 grade. Bendable: according to 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 adoption; energy efficiency: 夏天保 cold, winter insulation, PC board has more than ordinary glass and thermal conductivity (K value) of other plastics, glass insulation effect higher than the equivalent of 7% -25%; temperature adaptability: PC board does not occur at -40 ℃ cold crisp when not soften at 125 ℃, in the harsh environment no significant change in its mechanical, mechanical properties. Weather resistance: PC board can maintain the stability of the physical indicators in the range of -40 ℃ to 120 ℃. Artificial weathering test 4000 hours, yellowing degree 2, reducing the value of the transmittance of only 0.6%.
