our pc sheet Transparency :Maximum88%,low coefficient of thermal conductivity(K-value),good thermal insulation,the energy saving is 1.7 times higher than the one of glass with same thickness.The weight is only about one fifteenth of glass at the same thickness. Can be cold-bent,the safety radius of curvature is more than 175 times of its thickness. PC panel can maintains excellent properties in s wide temperature range from -40蚓 to 120蚓.After accelerated weathering test 4000h.ΔYI=2, ΔYT=0.6%.
pc sun sheet(Twin-Wall Polycarbonate Sheet) Light transmission:Sun panels 6mm thick can transmit 80% of light,while crystal hollow panels at the same thickness san transmit 40%,and the light through it will diverge and does not from a light band,which will effectively decrease the room temperature.Weather ability:Produced by duel-layer coextrusion technology,the surface of sun panels and crystal hollow panels are covered with a layer of high-density UV-adsorbing agent .they have excellent weather ability outdoors.having been used for a long period,they still maintain excellent optical and mechanical properties. Energy-saving:They have low coefficient of heat-fransmission and excellent heat-insulation property,especially crystal hollow panels by which the energy saved is 3-5 times of that by glass at the same size.Sound-insulation: the hollow structure and polycarbonate resin create a excellent sound-insulation property which effective reduce noise.Fire retardant:Through the test by the national quality supervision and lnspection center for fireproof materials,their fire retardant is up to B1 grade.Easy installation:PC sheet can notonly be cold bent,but also cold bent to arch shape,semi-circular shape and other shapes.the minimum bending radius is 175 times of the thickness of the sheet.Light weight:the weight of sun panels is 1/15 times of the glass at the same thickness.Temperature resistance:PC sheet has excellent property of tem perrature resistance.it can keep itsvarious physical propertes stable in the temperature fron -40蚓 to 120蚓.Dew free:No dew will form on the surface of the PC sheet in the temperature outdoor of 0蚓,23蚓 indoor and the relative humidity lower than 80%.
