Information & specification of Aluminosilicate glass
Aluminosilicate glass is typically used wherever pressure loads occur at temperatures above 300 °C.
The aluminosilicate glass from MAXOS production is characterized by a particularly high temperature
resistance of up to 375 °C.
For temperatures up to 300°C, you can use standard borosilicate glasses DIN7080/7081 (with mica).
A suitable mica protection can additionally protect the glass from aggressive media such as alkaline solutions and acids.
