Save on cost with lightweight materials
For years, DuPont has developed forward-thinking products and systems that impress with their lightweight designs. In trains, the standards for safety, more comfort and higher speed are increasing. Lightweight structures help reduce energy consumption and lower costs of your rolling stock.
High tensile interlayer
DuPont™ SentryGlas® offers new lighter, safer and more durable rail glazing solutions. This specific laminate can substitute traditional laminated glazing in terms of strength, and its reduced total weight makes it a fundamental attribute for rail design.

- Lighter weight: up to 40% compared to traditional laminated glass
- Higher strength when compared to traditional laminated glazing
- Higher durability makes open edges application and sealant compatibility possible
- Enhanced post-breakage behaviour: the interlayer stiffness keeps the fragment in place and can also withstand considerable load
