Physical Properties for Lexan® Polycarbonate 9034 Sheet

Lexan®* Polycarbonate 9034
Lexan®* 9034 uncoated polycarbonate sheet is the standard grade of Lexan® sheet for transparent protective glazing. High-impact Lexan® 9034 sheet may be an excellent candidate for primary glazing for economical protection against breakage or intrusion. A better insulator than glass, Lexan® 9034 sheet may contribute to lower energy costs.
