ntroduction:
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.
Outstanding thermal resistance
· Very good temperature stability
· Excellent resistance to thermal shock
· Can be thermally toughened
· Can be thermally shaped (3D)
