Borosilikat-Floatglas 3,3, Borosilikat Feuer

Borosilicate 3.3 serves as a material of truly functional and wide applications: 1). Household electrical appliance (panel for oven and fireplace, microwave tray etc.); 2). Environmental engineering and chemical engineering (Lining layer of repellence, autoclave of chemical reaction and safety spectacles); 3). Lighting (spotlight and protective glass for jumbo power of floodlight); 4). Power regeneration by solar energy (solar cell base plate); 5). Fine instruments (optical filter); 6). Semi-conductor technology (LCD disc, display glass); 7). Iatrology and bio-engineering; 8). Safety protection (bullet proof glass) Sizes Thickness 1.50 2.253.003.805.006.007.502.002.753.304.005.506.508.00Thickness tolerance±0.2±0.3Dimension Dimensions: 1150mm×850mm 1150mm×1700mm 1200mm×600mm other formats upon request Available thickness: 1.5mm--20mm Net sized glass of strengthening can be suppliedGlass of cut size is availableSize toleranceL≤1m ±1 1m L ≤2m ±2Physical Properties Density (at 25) 2.23±0.02g/3Modulus of elasticity68kN/mm2 Thermal Date Co-efficient of expansion(20-300)3.3±0.1×10-6Softening point820±10Strain point516±10Heat conductivity at 901.2W/mk Caloricity(20-100) 0.82KJ × (kg×K)-1Thermal shock resistanceStrengthening type180K300KIdentical temperature differenceStrengthening type100K300 KMaximum working temperature Short time(<10h):Long time(>10h):500 450 Electical Property Specific resistance lgρ 8.0Ω×cm at 250tanσ(120) Dielectric dissipation fraction 38×10-4 Dielectric constant ε=4.7Borosilicate fire resistance glass Fire resistance glass for doors and windows Fire resistance glass for cut off Sealed insulating glass Glass used in curtain walls Fire resistance glass for celling ,floor Glass type Borosilicate GlassManufacturingFloat processColourClearIntegrityC classitemExecutive standardGB15763.1-2001Sizes Thickness6 81012Thickness tolerance±0.2±0.3±0.3±0.3Max.1500×3000Min.100×100(smaller sizes may be possible on request)Size toleranceL ≤1m ±1 1m L ≤3m ±2Physical Properties Density (at 25) 2.28±0.02g/3Modulus of elasticity68kN/mm2Thermal Date Co-efficient of expansion (20-300)4.0±0.1×10-6 Heat conductivity at 901.26W/mk
