SCHOTT BOROFLOAT® Borosilicate Glass
Float-quality borosilicate glass with low thermal expansion and a degree of tolerance towards thermal shock and temperature gradient on and in the glass.
Ideally suited for sight and window glass where resistance to high temperatures is required. 1.1 to 21mm thickness available from stock.
BOROFLOAT® glass is a borosilicate superior float glass.
Whether it be as an oven door window or a biochip used in modern medical technology, or as a component utilized in theatre spotlights, film projectors or diving robots, few glass types can claim to be as versatile as BOROFLOAT® glass. Even space exploration has adopted the material as a key component in research telescopes, enabling scientists to view fascinating, new dimensions.
• Outstanding thermal resistance
A particularly low coefficient of thermal expansion is what makes BOROFLOAT® glass remarkably resistant to high temperature levels. Our borosilicate glass is proven to stand up to high and fluctuating temperatures typical of applications such as high-performance lamps, cinema projectors and inspection panels for chemical reactors. Even with applications where rapid cooling down from higher temperatures is the requirement, BOROFLOAT® glass easily passes the test. For example, the temperature difference between a hot panel center and a cold panel edge.
• Exceptionally high transparency
The performance requirements for optical mirrors are extremely rigorous as slight deviations can have significant impacts on the outcome of specific performance. Thermal stability is a must if mirrors are used in environments subjected to temperature changes. Excellent surface quality combined with exceptionally high transmission and reasonable cost are other attributes that engineers consider when specifying their material of choice. BOROFLOAT® glass meets such demanding requirements and has been used for sophisticated optics around the globe
• High chemical durability
• Excellent mechanical strength
