BG33 borosilicate glass redefines durability and clarity. Its coefficient of expansion (3.3±0.1x10-6) prevents cracking under thermal stress, while a thermal shock resistance of >=125K suits harsh conditions. From semiconductor manufacturing to pharmaceutical packaging, BG33 maintains chemical inertness and optical purity. Custom sizes (e.g., 1150x1700mm) and thickness options empower designers to innovate. We support global clients with samples (freight-covered by customers) and OEM services. Trust our decades of expertise to meet ISO-certified standards.
