Product Description
Borosilicate glass performance
1). Mechanical Performance Density ρ 2.23±0.02g/cm3
2). Thermodynamic Performance
Thermal expansion coefficient (0-300) 3.3±0.1×10-6K-1
Softening point 820±10°C
Strain point 516±10 Caloricity (20-100) 0.82KJ × (kg×K)-1
Thermal coefficient 1.2W×m×K-1
3). Chemical Performance
Water resistance ISO719/DIN12111 HGB1/ISO720 HGA1
Acid resistance ISO1776/DIN12116 1
Alkali resistance ISO695/DIN52322 A2
4). Optical Property
Refractive index Nd: 1.47384 Transmittance spectrum curve
5). Electrical Property
Specific resistance lgρ 8.0Ω×cm at 250
Dielectric dissipation fraction tan σ (1 megacycle at 20): 38×10-4
Dielectric constant ε=4.7
tempered borosilicate glass is one of transparent colorless glass, through wavelength is between 300 nm to 2500 nm, transmissivity
is more than 90%. Coefficient of thermal expansion is 3.3. It can acid proof and alkali , the high temperature resistant is about
450°C. If course handling , the high temperature resistant can reach 550°C or so. Apply to lighting fixture , chemical industry ,
electron, high temperature equipment and so on.
Difference between borosilicate3.3 and borosilicate 4.0:
High Borosilicate Glass 3.3
Heat resistant
Hydrolytic Resistant
High Chemical Resistant
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)
High Borosilicate Glass 4.0
Product characteristic
Excellent visual effect
Powerful effect on fire resistance
High resistance to thermal shock
Without dealing with homogeneous, burst non-self
Application
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 ceiling, floor
