Reference # : Model No :

DURATAN® pre-stressed glass is based on the DURAN® borosilicate glass 3.3 which has great acid resistance, and outstanding chemical and physical material properties. Additionally, the tube wall of the DURATAN® glass is pre-stressed through a thermal toughening process. Applications include safety lights in explosive atmospheres, sight glasses and display cylinders for product presentations, sight glasses in pipeline construction, tunnel lighting, outdoor lighting, interior and exterior architecture, art and design.

Benefits

Two to three times more resistant to tension and mechanical shock than untreated glass. Advantages over plastics include high scratch resistance and light stability, high resistance to UV radiation, as well as high chemical resistance and temperature-change resistance. Enhanced safety, when damaged it shatters into fine fragments, similar to tempered safety glass. Shock resistance has been tested with ball-drop tests.
