DuPont™ SentryGlas® Ionoplast Interlayer Now Offered on Rolls
New 35-mil Ionoplast Rolled Sheeting Helps Manufacturers Advance the Safety and Strength of Laminated Glass
"Because it's up to 100 times stiffer and 5 times tougher than traditional laminating materials, DuPont™ SentryGlas® has become popular among structural glazing specialists and leading-edge glass laminators," said Ron Hull, DuPont global business director for advanced interlayers. "While SentryGlas® interlayer sales growth has outpaced other interlayer product growth during the past decade, many laminators were asking for roll stock to further expand their use of this innovative safety material and we're happy to respond."
SentryGlas® interlayers are now available to laminators in flat sheet form, in thicknesses of 35-, 60-, 90- and 120-mil, and as rolled sheeting, at 35-mil thickness. The new, rolled sheeting comes in standard sizes of 48 inches (1.21m), 60 inches (1.52m) and 72 inches (1.83 m) wide by 200 meters, and 60 inches (1.52 m) wide by 50 meters, depending on customer requirements.
"Many laminators will find useful handling and productivity advantages when using rolled SentryGlas® interlayer, versus flat-stored sheets," explained Hull. "Because the 35-mil rolled stock is so convenient for them, some laminators plan to use it in multiple plies to meet thicker interlayer requirements."
The new roll-stock version of SentryGlas® is made using the same raw materials as flat sheets, so laminated glass strength and structural advantages realized with the new roll stock are expected to be the same as found previously with SentryGlas® in properly laminated structures.
DuPont™ SentryGlas® interlayers have been a key element in some of the most noteworthy laminated glass projects in the world, including Apple retail stores worldwide, rooftop deck rails at the Marina Bay Sands in Singapore, and specially enabled glass structures, such as the Willis Tower Ledges in Chicago and the Lincoln Center's Alice Tulley Hall in New York. The interlayer's extra stiffness and strength gives SentryGlas® ionoplast a routine advantage in safer glass balustrades, overhead canopies, clear facades, high-security applications and glass designed for use in extreme wind zones.
