Providing superior structural capacity versus conventional PVB, Saflex Structural interlayer is a PVB interlayer designed for applications where interlayer rigidity and high glass adhesion requirements for laminated glass are critical. In properly designed systems, Saflex Structural is capable of containing glass shards at high and low temperatures after impact and under load—even in open edge laminated glass.
Enabling glass reduced thickness
Thanks to the strength and stiffness of Saflex Structural interlayer, laminated glass can sustain higher loads or be made thinner while maintaining the same load capacity while keeping the same load and area as compared to conventional laminated glass. It is compatible with most glass types, including annealed, heat-strengthened, and fully tempered glass. Heat-strengthened glass combined with Saflex Structural interlayer offers advantages such as reduced optical distortion, resistance to thermal stress breakage, lower risk of spontaneous breakage, and good residual strength after breakage.
Compatible with coatings and Vanceva colors
Saflex Structural is formulated to provide strong resistance to delamination in open edge exposed applications and offers good compatibility with most visibly reflective, low emissivity, and ceramic frit coatings, as well as sealants. Additionally, it is compatible with Vanceva Colors and Earth Tones interlayers , allowing architects and designers to create safe, durable glass designs without compromising style or comfort.
