SaflexTM Structural

Saflex interlayers are plasticized polyvinyl butyral (PVB) sheeting produced by Eastman and its affiliates. These interlayers are bonded through a heat and pressure process to two or more pieces of glazing to produce laminates with impact and glass containment properties. Saflex Structural PVB interlayer is a tough, resilient film produced from plasticized PVB resin. It is designed specifically for applications where increased interlayer rigidity and high glass adhesion are required compared to conventional glazing interlayers. Saflex Structural PVB combines stiffer rheology with features such as glass containment upon breaking, UV screening, low haze and the ability to laminate thick multiply glass. This makes it an excellent choice for most structural applications such as: balconies, floors, fins and stair treads. It may also be used to adhere the glass spall shield layer for bullet resistant glazing, glass applications where creep at higher temperatures is a concern and areas where edge effects from sealants or exposed laminate edges need to be minimized. When used as part of a multi-interlayer laminate glazing system, Saflex Structural can provide increased infull retention due to lower deflection as compared to glass without it. Most common standard roll lengths are 247 and 250 meters in the thickness of 0.76 mm.
