Introduction to the Trosifol™ Business

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® & 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 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 your 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.
