Our ultra-clear solar float glass is manufactured using only the highest quality materials including premium sand, natural ores and carefully selected compounds. The mixture is melted at high temperatures, and the molten glass is then spread, polished and shaped through a tin bath. This top-quality float glass boasts a smooth, flawless surface, excellent optical clarity and impressive resistance to chemical attack and mechanical stress. Due to its excellent stability and elasticity, our ultra-clear solar float glass is ideal for a variety of solar panel applications. With its exceptional resistance to acids, alkalis and other environmental elements, our ultra-clear solar float glass ensures the long-term reliability and efficiency of your solar panel system. Trust the durability and high performance of our products to ensure successful and profitable solar panel installations.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: 2.5mm~10mm;  2.Standard thickness: 3.2mm and 4.0mm  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
