Polycarbonate Sheet (CT303100/21)



This Polycarbonate sheet grade Makrolon GP clear 099 is a clear transparent sheet with high light transmission.

Solid Makrolon® sheets are clear, polished, UV-stabilized polycarbonate sheets. They offer extreme impact strength that exceeds the physical properties of other products of their class. Makrolon sheets resist temperatures of -100 to +120 °C, exhibit high optical clarity and have a good fire rating.
