Product Description Borosilicate glass tubing 3.3 Properties:High chemical resistance: borosilicate glass 3.3 is very resistant to water, neutral and acid solutions, strong acids and their compounds. Outstanding transmission: borosilicate glass 3.3 is very transparent, it has stable transmission from UV-A to IR range.Resistant to thermal shock: it is perfect material in contact with fire and high temperatures due to its high working temperatures and thermal shock.Dimensions range(mm)Outside diameter(OD): 3-400mmWall thickness(WT): 0.4-13mmLength(L): 1200-2000Applications:Due to its thermal shock resistance, chemical resistance and easily processed features, borosilicate glass tube 3.3 is widely used in laboratory devices, chemical equipment, solar thermal collector, kitchen ware and giftware. Support:We have engineers with many years experience in glass tubing processing and special knowledge in glass properties and annealing practise. We can provide free advice and trainingNo.Physical PerformanceNumberical ValueUnit1Coefficient of Mean Linear Thermal Expansion(20oC-300oC)3.3±0.110-6/K2Transformation Temperature525±15oC3Softening Point820±10oC4Working Point1260±20oC5Density at 20oC2.23±0.02g/cm36Mean Thermal Conductivity (20oC-100oC)1.2w/m2k7Refractive Index0.92 Chemical Data Hydrolytic Resistance at 98oCISO719-HGB 1Hydrolytic Resistance at 121oCISO720-HGA 1Acid Resistance ClassISO1776-First Class Chemical Composition SiO281%B2O313%Na2O+K2O4%Al2O32%
