The main components of borosilicate are silica and boron trioxide. It benefits from having very low coefficients of thermal expansion making it more resistant to thermal stock than other common glass. As the glass is less susceptible to thermal stress, it can withstand temperature differentials of 165°C.
In addition, it has excellent scratch and abrasion resistance and has high transmission and optical clarity.
These physical properties make it ideal for various applications including lighting, electronics, and lab equipment and cookware.
Other common terms for borosilicate are Pyrex™, Borofloat and Suprax™.
