Saflex® DG structural interlayer has been awarded the AbZ by Deutschen Institut für Bautechnik

Eastman Chemical Company (NYSE:EMN) is proud to announce that Saflex® DG structural interlayer has been awarded the General Technical Approval (Allgemeine Bauaufsichtliche Zulassung or AbZ) by the German Institute for Building Technology (Deutschen Institut für Bautechnik -DIBt).

Saflex DG structural interlayer is the first polyvinyl butyral, or PVB, interlayer with structural performance to receive the AbZ approval to be used as laminated safety glass.   In receiving an AbZ from the DIBt, Eastman demonstrated  that the Saflex® DG interlayer can indeed be used to produce laminated safety glass and that the resulting laminate has the same safety properties as a laminate made with an interlayer which fulfills the tensile and elongation requirements.The laminated safety glass can be used as laminated safety glass (VSG) in the sense of “Technical regulations for the use of linear supported glass (TRLV),” the “Technical regulations for the design and execution of point-mounted glazing (TRPV),” and the “Technical Rules for the use of safety glazing (TRAV)” are applied.

“With this product, we are able to bring an entire new dimension to structural glazing,” says Kevin Moens, Eastman Global Business Director – Advanced Materials Interlayers. “Glass is a key design element for European architects and this added capability will enhance the performance choices available to them.” 

Saflex DG41 PVB interlayer has already been used in three landmark projects worldwide including balconies and railings for the new Ghelamco Arena in Gent Belgium, the new Beijing Aegean shopping mall in China, and the soon-to-be-completed Corning Museum of Glass in Corning, New York, where the product was combined with Vanceva® Polar White PVB for use in the glass façade. 

Saflex DG41 structural interlayer is a tough, resilient film produced from plasticized polyvinyl butyral (PVB) for structural glazing. It is designed specifically for applications requiring superior structural capacity, higher uniform load capacity, increased interlayer rigidity and high glass adhesion, making it ideal for glass flooring, curtain walls, overhead glazing and railing. In a properly designed system, Saflex DG41 interlayer is capable of keeping glass intact at high and low temperatures, even after impact and under load.

Saflex DG interlayer provides architects, designers and property owners design flexibility as it is compatible with other Saflex and Vanceva® products. It is recyclable and available in roll form. Plus, it combines the benefits of a rigid interlayer with the features of glass containment, UV screening, edge stability, clarity and noise abatement.

Eastman’s Saflex brand of PVB interlayers is the most trusted name in PVB interlayer technology for laminated glazing, delivering outstanding performance and durability and backed by reliable and knowledgeable service. As a result, Saflex interlayers are found in nearly 40 percent of laminated architectural and automotive glass worldwide.
