The new alkaline-earth aluminosilicate glass AF37 is characterized by a large number of exceptional physical and chemical properties. The speciality glass from SCHOTT is alkali and arsenic free in synthesis, and has a high chemical durability. Resulting from the low coefficient of thermal expansion, AF37 glass offers a high heat resistivity. It features a low shrinkage which is of great importance to many electronics and display applications. The thin glass material is made by using advanced float glass technology. It profits from all advantages of this manufacturing process. Therefore the natural surfaces of AF 37 already show a good flatness and low micro roughness. Often the material can be utilized without an additional mechanical polishing step, resulting in significant cost savings to the user. AF37 glass has a low thickness tolerance, a good TTV (total thickness variation) and is available even at large dimensions. As a result of its low density, AF37 is relatively light weight, which is an important advantage exceedingly in display applications. For further information, please contact us.
The production of AF37 has been discontinued. Therefore large material quantities cannot be quoted anymore. We still have some stock for smaller orders available.
