Hydrolytic resistance according to DIN ISO 719:.Coefficient of mean linear thermal expansion :Ĥ,5 × 10 -6/K (20-300 ☌ static measurement).*Caused by marginal impurities in the raw materials, and resulting from the manufacturing process, an alkali content of 0,2 percent of weight might be possible in AF 45. For all thicknesses below 0,7 mm, AF 32 ® eco is a new perfect alternative product to AF45. Possible alternative near-zero alkali glass materials at 0,7 mm and 1,1 mm are 1737 and EAGLE2000. We still stock some remaining AF 45 material at some thicknesses. Important note: SCHOTT discontinued the production of AF 45 glass a long time ago.

To request a quote for windows or substrates made of AF 45 alkali-free glass with specific dimensions, please choose a thickness from the table in the specifications or click the button below. Its high transmission in the visible wavelength range enables many optical applications in optoelectronics and sensor technology. The glass features excellent thermal resistance and a low coefficient of thermal expansion. Because of the high-quality fire-polished surfaces of AF 45, there is no need to polish the glass surfaces before use in most instances. Due to the unique properties of AF 45, this sheet glass is an excellent choice for many specialty display glass applications. Partially available in 48 h Express-ServiceĪF 45 thin glass from SCHOTT is modified borosilicate glass with a high content of BaO and Al2O3. D 263 T (Thin and ultra-thin borosilicate display glass).
