SCHOTT Robax® Heat Resistant Glass


SCHOTT Robax® is a transparent ceramic glass that is extremely heat resistant. It can withstand temperatures up to 1400°F (760°C) due to its low coefficient of thermal expansion. Robax® has high transmission in the visible and infrared spectrums, which makes it an excellent choice as a window in high temperature applications such as fireplaces and stoves. Robax® also has ultra-violet (UV) blocking characteristics, which makes it suitable for UV blocking shields.


While Robax® has good transmission and heat resistant properties; it has a slightly textured surface and an amber colored hue, and therefore may not be desirable for coatings or other high tech applications.


Abrisa Technologies can provide Robax® in thicknesses of 3mm and 5mm, and with a maximum sheet size of 62” x 33”.
