Kuraray™ Trosifol® Ultraclear PVB Film

The world's first PVB safety glass was produced in 1938 by DuPont in the United States, originally developed to prevent injuries caused by shattered glass on the battlefield.
As technology advanced, safety glass began to emphasize not only protection but also aesthetics.

Kuraray has surpassed DuPont’s technology and upgraded its production lines, launching Trosifol™ Ultra Clear, a German-made, next-generation ultra-clear PVB interlayer considered the most advanced in the world.

1️⃣ Exceptional Clarity
Standard PVB typically has a yellowness index of around 6–7.
Kuraray SentryGlas® achieves < 1.5, and Ultra Clear reaches only 2, delivering a pure, crystal-clear appearance.

2️⃣ High Adhesion & Low Risk of Delamination
Some glass manufacturers in Taiwan struggle with moisture control, leading to bubbles, haze, or edge delamination.
Ultra Clear PVB offers high adhesion and excellent stability, significantly reducing the risk of glass rejection when standard humidity controls are followed.

3️⃣ Passed Rigorous Testing
Both Trosifol™ Ultra Clear and SentryGlas® have passed 3,000-hour, 5% salt spray tests, demonstrating outstanding durability and weather resistance.

4️⃣ Premium Yet Affordable – The Clear Choice
Combining aesthetics, durability, and cost efficiency,
Ultra Clear is the ideal solution for clients seeking high-quality laminated glass without unnecessary expense.
