Trosifol – For laminated safety glass that meets the highest requirements

Glass is irreplaceable in many applications – in architecture, the automotive industry, shipping and railcars. For the glass industry, Kuraray markets Trosifol®, the world's broadest portfolio of innovative laminated glass solutions. You too can use the versatile technical and optical possibilities offered by Trosifol interlayers for laminated safety glass.

Crystal clear for maximum freedom of design

Trosifol® interlayers are available in many different colors and as structural interlayers. Alternatively, they can be printed to meet individual requirements, allowing maximum freedom of design. In addition, Trosifol® interlayers have the world's lowest yellowness index – perfect for laminated glazing with optimum brilliancy for windows, doors and other glass elements.

For demanding structures and safety

Trosifol products can be used for the most demanding applications, from glass floors, overhead glazing, stairs and bridges to hurricane-proof glass facades. Trosifol is world’s only producer of SentryGlas® ionoplast interlayers, which are five times stronger and up to one hundred times stiffer than conventional interlayers. In addition, bullet-proof and anti-intrusion glazing concepts meet the highest safety standards.

From acoustic to UV protection for feel-good buildings

Trosifol functional interlayers can be used to create optimum conditions in buildings. For example, acoustic interlayers make noise insulation far more effective. UV protection protects works of art in museums and furniture and fittings from fading as a result of exposure to sunlight. By contrast, interlayers with high UV permeability make sure animals and plants receive essential vitamin D.

Road and rail safety

For transportation safety, Trosifol offers high-quality, lightweight laminated glass solutions. For example, they hold the glass when it shatters, so people in cars, trains and buses are not injured by sharp splinters.

Use Trosifol in your laminated safety glass and benefit from the broad portfolio and expertise of Kuraray Trosifol, the leading producer of PVB and ionoplast interlayers.
