Borosilicate glass is a specialized glass known for its high thermal shock resistance, chemical durability, and optical transparency. It is widely used in laboratory, industrial, and optical applications. Our CNC machining services enable high-precision fabrication of borosilicate parts, including custom windows, tubes, plates, and fluidic components.
Borosilicate is a silica-based technical glass that incorporates boron trioxide (B₂O₃) to significantly reduce its coefficient of thermal expansion. It exhibits superior resistance to temperature changes, chemical attack, and optical distortion, making it ideal for scientific, high-temperature, and chemically aggressive environments.
We offer CNC machining for high-purity sintered Borosilicate Glass.
