Trosifol® announces the launch of SentryGlas® TW ionoplast interlayer to extent the Trosifol® Structural Offering

Kuraray’s Trosifol® Business has announced the commercial launch of SentryGlas® TW ionoplast interlayer for laminated safety glass, which combines all the technical benefits and structural properties of SentryGlas® ionoplast interlayer i.e. safer, lighter, tougher structural glass solutions with a variety of white color effects that provide both a pleasing aesthetic effect and a sense of privacy.

The official launch of translucent white SentryGlas® TW interlayer follows a number of successful building projects that have benefited from the new interlayer like the College Football Hall of Fame and Chick-fil-A Fan Experience in Atlanta, Georgia, USA. This three-storey, 94,000 square feet (8,733m2) museum uses SentryGlas® TW interlayer for the exterior glass façade and the interior entrance tunnel ceiling. Jennifer Schneider, Structural and Security Market Manager, Trosifol® Business commented: “Architects and glazing contractors that desire a structural interlayer and want the option of a white color effect now have an option. They can now specify an interlayer with the known technical advantages and structural properties of SentryGlas® but also has an added feature of providing privacy and a translucency effect. SentryGlas® TW provides a unique combination of white color effect and structural properties that no PVB interlayer can possibly match.” SentryGlas® TW interlayer gives architects much more freedom in their designs, combined with the improved structural properties of SentryGlas®. For example, the interlayer’s stiffness and strength (SentryGlas® ionoplast interlayer is 100 times stiffer and 5 times stronger than traditional PVB) help to create lighter and safer structural glass that can withstand greater loads and harsh conditions. As well as providing excellent post-breakage performance, SentryGlas® TW interlayer also offers excellent durability and edge stability, even when exposed to extreme weather conditions – an important consideration in minimally supported applications such as glass canopies, balustrades, exterior facades and flooring. Available to laminators on roll, SentryGlas® TW ionoplast interlayer can be stacked to achieve different visible light transmission properties, giving designers even more freedom. For example, a 65% visible transmittance (Tvis) is achieved by stacking two plies of 31mil (0.80mm) thickness interlayer together during the lamination process. The result is an approximate overall interlayer thickness of 62mil (1.60 mm). A higher or lower Tvis be achieved by varying the number of plies of SentryGlas® TW interlayer.

“In accelerated outdoor weathering tests, SentryGlas® TW interlayer showed no signs of discoloration after 10 years,” added Jennifer Schneider. Like SentryGlas® ionoplast interlayers, SentryGlas® TW interlayer has achieved Miami-Dade County approval for use in hurricane impact resistant glazing applications.

SentryGlas® TW interlayer on rolls is available in widths of 122 cm (48 in), 153 cm (60 in) and 183 cm (72 in), in lengths of 200 meters (656 ft.). 153 cm (60 in) width is also available in 50-meter (164 ft.) roll lengths.


About Trosifol® Structural:
SentryGlas® TW is part of the Trosifol® Structural offering. The use of laminated glass in structural glazing applications has become preferred as a safer choice to monolithic tempered or heat strengthened glass due to the glass retention characteristic of laminated glass resulting in greatly improved post glass breakage properties providing enhanced safety. With Trosifol® ES Stiff PVB and SentryGlas® ionoplast, Trosifol® offers different options designed to best meet structural glazing performance and design requirements.


About Trosifol®
Trosifol® belongs to the Kuraray Group and is a leading global producer of PVB and ionoplast interlayers for laminated safety glass applications in the architectural, automotive and photovoltaic industries.
The evolution of the Trosifol® and GLS merger (DuPont) over the last two years has resulted in consolidation of the Trosifol®, SentryGlas® and Butacite® product brands into a single brand: the new Trosifol®.
We at Trosifol® now offer the world’s broadest portfolio of innovative glass-laminating solutions, including structural and functional interlayers for safety and security applications, sound insulation and UV protection. For decorative applications, we supply colored interlayers, digitally printable films and other innovative products for interior design projects. Our UltraClear films exhibit the lowest Yellowness Index (YID) in the industry. Trosifol® is in the perfect position to be the preferred partner for laminated safety glass applications – serving the ever-changing demands of the global glass industry with seven worldwide production sites and five R&D centers.
First time to present the new product portfolio worldwide will be at the (architect’s event in NYC), the 24th ‘glasstec’ – the world’s biggest trade fair for the international glass industry, 20 – 23 September 2016 in Dusseldorf/Germany, and the CTBUH 2016 conference in Shenzhen, Guangzhou, Hong Kong/China, 16 – 21 October 2016.
