Advanced Aluminosilicate Glass Panels for Enhanced Alkali Resistance

Advanced Aluminosilicate Glass Panels for Enhanced Alkali Resistance

Aluminosilicate (alkali-resistant) glass panel is designed for applications where conventional soda-lime glass cannot withstand strong alkaline media, elevated temperatures or frequent thermal cycling. The increased alumina content and controlled manufacturing produce a material with:

• Outstanding resistance to alkali corrosion and many aggressive chemicals.

• Low coefficient of thermal expansion for excellent thermal-shock performance.

• Improved mechanical strength and dimensional stability for precise mounting and machining.

Key benefits

• Long service life in caustic and alkaline environments

• Stable optical clarity for visual monitoring and instrumentation

• Low thermal expansion → high resistance to thermal shock

• Precise machining for leak-tight installation and integration

• Safety options (lamination) to retain fragments on breakage

Typical applications

• Sight windows and sight glasses for reactors, vacuum pans and vessels

• Level gauges and instrument sight ports

• Chemical and petrochemical process equipment exposed to caustic media

• Laboratory apparatus, pilot plants and research vessels

• High-temperature or thermal-shock prone equipment requiring durable optical access
