20120088101 | MULTILAYER INTERLAYER POLYMER FILM FOR FIRE-SCREEN GLAZINGS AND RELATED FIRE-SCREEN PRODUCTS - A multilayer interlayer polymer film for use within and a high clarity and high efficiency fire-screen glazing or related fire-screen product uses a particular ordering of layers. The ordering of layers includes: (1) a core layer comprising one of a sulfur containing thermoplastic polymer material and a fluorine containing thermoplastic polymer material; (2) at least one intermediate layer laminated to the core layer and comprising the other of the sulfur containing thermoplastic polymer material and the fluorine containing thermoplastic polymer material; and (3) at least one skin layer laminated to the at least one intermediate layer and comprising a thermoplastic polyurethane material. The film provides cost effective and efficient fire-screen glazings and related fire-screen products due to the thermoplastic polyurethane polymer material and the sulfur containing thermoplastic polymer materials which also may be used in absence of the fluorine containing thermoplastic polymer material to provide an additional embodiment. | 04-12-2012 |
20120088082 | Thermoplastic Multilayer Interlayer Polymer Film and Related Glass Laminate Composite Including Same - A multilayer interlayer polymer film and a high clarity safety glass laminate made using the same include: (1) a core layer comprising one of an ionomer polymer material and a thermoplastic polyurethane polymer material; (2) at least one intermediate layer laminated to the core layer and comprising the other of the ionomer polymer material and the thermoplastic polyurethane polymer material; and (3) at least one skin layer laminated to the at least one intermediate layer and comprising a non-ionomer polyolefin polymer material. The multilayer interlayer polymer film provides the high clarity safety glass laminate with enhanced performance with respect to optical properties and manufacturability. In an alternative embodiment the at least one skin layer may be omitted when the intermediate layer comprises a thermoplastic polyurethane material with adequate adhesion to glass. | 04-12-2012 |
