BF33 glass, also known as BOROFLOAT® 33 borosilicate glass, is a high-performance float glass material with excellent thermal stability, high optical transparency, low thermal expansion, and strong chemical resistance. It is widely used in semiconductor processing, MEMS devices, microfluidics, optical windows, sensor packaging, laboratory instruments, and high-temperature observation applications.
Compared with ordinary soda-lime glass, BF33 glass offers better dimensional stability under temperature changes and improved resistance to chemical corrosion. Due to its low coefficient of thermal expansion, BF33 is also suitable for silicon-glass bonding, wafer-level packaging, and precision glass substrate applications.
