2.0mm 2.5mm 3.0mm black white printed backside float glass is also called flat glass which mainly used on back of BIPV panel which also called Double glasses panel, BIPV panel is a thin layer of optoelectronic semiconductor which converting solar energy into electricity. By considering its efficiency, we are using High- transmittance and low reflection glass for its panel. This high strength glass maintains the best image quality by eliminating unwanted distortions with the advanced optical technology.9.Density: 2.5 g/CC 10.Young's Modulus: 73 GPa 11.Tensile Strength: 42 MPa 12.Hemispherical Emissivity: 0.84 13.Expansion Coefficient: 9.03x10-6/° C 14.Softening Point: 720 ° C 15.Annealing Point: 550 ° C 16.Strain Point: 500 ° C1.Thickness: 2.0mm~10mm;  2.Standard thickness: 2.0mm.3.2mm and 4.0mm 5.0mm 3.Thickness Tolerance: 3.2mm± 0.20mm; 4.0mm± 0.30mm  4.Max size: 2250mm× 3300mm  5.Min size: 300mm× 300mm  6.Solar Transmittance (3.2mm): ≥ 91.6%  7.Iron Content: ≤ 120ppm Fe2O3  8.Poisson's Ratio: 0.2
