Exolon® Silent Sound
- Chemical Family
- Polycarbonate (PC)
Exolon® Silent Sound sheets are clear, polished, UVstabilized polycarbonate sheets and available as extended UV and Abrasion-resistant AR (anti graffity like)/ Bird friendly BF version. They offer extreme impact strength that exceeds the physical properties of other products of their class. Exolon® sheets resist temperatures of -100 to +120 °C, exhibit high optical clarity and have a good fire rating. Exolon® Silent Sound sheets meet the sound technical requirements for noise reduction and the demands of road and railway safety, stability such as form and aging stability. Exolon® Silent Sound UV can be bent cold and also manufactured flat. Furthermore Exolon® Silent Sound sheets can be thermoformed, cold-curved and machined with ease.
