TROSIFOL® – YOUR GLOBAL PARTNER FOR LAMINATED SAFETY GLASS

Trosifol® – part of the Kuraray Group – 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 DuPont Glass Laminating Solutions

(GLS) merger 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 print-

able 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 your preferred partner for lami-

nated safety glass applications – serving the ever-changing demands of the

global glass industry with seven worldwide production sites and five R&D

centers.

STRUCTURAL INTERLAYERS FOR DEMANDING APPLICATIONS

Structural interlayers make glass panels stronger, expanding the possibili-

ties of architectural glazing designs. Trosifol® offers the world’s broadest

portfolio of structural interlayers. That gives architects and structural en-

gineers a choice of solutions to address the precise needs of their specific

applications. Trosifol® Extra Stiff is a stiff PVB interlayer and SentryGlas® is

based on a unique ionoplast technology. Both interlayers excel over stan-

dard PVB and are UltraClear – offering the lowest YID on the market – mak-

ing them ideal, e.g. for use with low-iron glass, where long-term optical

clarity needs to be assured.

Both products have the general approval of the building authorities

issued by the German Institute for Construction Engineering (DIBt), Berlin.

SentryGlas® meets the strict performance requirements of Miami Dade

County, Florida.

High performance structural interlayers from Trosifol® give designers much

more freedom to exploit the aesthetics of glazed features. The use of lami-

nated glass is now preferred by leading designers as a safer choice – com-

pared to monolithic tempered or heat-strengthened glass – due to enhanced

glass-retention characteristics. This is demonstrated by greatly improved post

glass-breakage properties, providing enhanced safety.

WEATHERING THE STORM – HURRICANE-PROOF GLAZING

Hurricane-impact-resistant glazing is capable of resisting

violent storms and can help protect against the impact

forces created by large and small flying debris. This type

of glazing is often mandated in hurricane-prone regions

to protect the integrity of buildings and their occupants.

The choice of interlayer depends on the specific de-

sign requirements and local building codes. All Trosifol®

Hurricane Glazing products have Miami Dade County NOA

(Notice of Acceptance) certificates.

Trosifol® is the only PVB manufacturer that offers both mono- and

multilayer acoustic film and, as a result, can offer the perfect solution

for any glazing application.

Both films offer outstanding sound insulation with the advantages of

conventional PVB film. Compared to laminated glass with standard PVB

film, sound attenuation can be 5 dB greater. R W values over 50 dB can

be achieved with both products.

CLARITY COMES AS STANDARD

Aesthetics are not short-term phenomena. Architects, designers, engineers and consultants

expect their structures to remain visually appealing and in terms of glazing, retaining their

clarity for many years. They must also balance structural requirements with aesthetic

appeal; as a result, YID is an incredibly important factor when specifying interlayers.

SentryGlas® and Trosifol® UltraClear films exhibit negligible inherent color

and excellent long-term environmental stability. As a result, they provide

the lowest YID on the market.

This visual neutrality results in a measurable improvement, especially in

laminated glass that deploy low-iron glass. The result is brilliant uniformity

across a wide range of applications.

UV CONTROL: PROTECT OR TRANSMIT

Ultraviolet (UV) light is vital to life, but too much UV in the

315 to 400 nm range can be particularly damaging, not only

to human skin, but also to plastics, pigments and paints.

To cater for varying needs of different applications, Trosifol®

offers solutions that either totally block UV wavelengths or,

unlike standard PVB, offer complete spectrum transmission.
